Definitions

  • the invention relates to a reciprocating compressor for a refrigerant circuit, comprising a crankcase, in which a collecting space for lubricant is arranged, a cylinder housing in which at least one reciprocating piston is oscillating, a cylinder housing final valve plate in which at least one inlet valve and an outlet valve are arranged and a cylinder head in which a suction gas guide extending to the inlet valve and a pressurized gas guide leading away from the outlet valve are provided.
  • Such reciprocating compressors are from the GB-A-1 244 105 , the US 3,713,513 A , the EP 0 064 018 A1 , the US 2,150,487 A1 and the DE 197 21 44 U known.
  • a line between the crankcase and the suction gas guide is provided, which only serves to equalize the pressure.
  • the invention is therefore based on the object to improve a reciprocating compressor of the generic type such that can avoid excessive accumulation of lubricant.
  • the advantage of the solution according to the invention is the fact that by such an embodiment, there is the possibility to suck lubricant from the plenum and supply the suction gas, which then conveys this lubricant through the reciprocating compressor and further promotes the pressure gas guide in the refrigerant circuit, for example, to the next compressor in the Refrigerant circulation.
  • the inlet opening in the collecting space is arranged so that it predetermines a predetermined position of a surface level of a lubricant bath.
  • the inlet opening of the lubricant suction channel provides a lowest surface level of the lubricant bath which can be achieved by suction of lubricant via the lubricant suction channel.
  • an advantageous solution provides that the lubricant suction duct extends at least in sections through a tube projecting into the crankcase.
  • This pipe preferably has the inlet opening, so that the position of the inlet opening can also be defined by positioning the pipe in the crankcase.
  • the lubricant suction duct extends at least in sections in the crankcase, that is, is formed in a wall of the crankcase and thus at least for this section no additional pipe is required.
  • the position of the inlet opening of the lubricant suction channel can also be fixed in a simple manner and thus the minimum level of lubricant that can be achieved by suction can be determined.
  • the region having the outlet opening of the lubricant suction channel lies in a constriction of a nozzle.
  • An alternative solution provides that the area of the suction gas guide having the outlet opening of the lubricant suction duct lies downstream of a throttle device in the suction gas guide in the flow direction of the suction gas flow.
  • Such a throttle device allows, for example behind the throttle point, at least temporarily, to lower the static pressure far enough that a pressure gradient between the plenum in the crankcase and the region of the outlet opening in the Sauggas operation occurs and thus takes place a suction of lubricant from the plenum.
  • the throttle device as a constantly effective throttle point, for example, by a very cost-effective aperture, realize that, however, unfolds a constant throttle effect.
  • Another advantageous solution provides that an adjustable throttle device is provided, which opens up the possibility, for example, depending on the size of the suction gas flow, the throttle effect and thus adjust the static pressure in the area between the throttle point and the inlet valve.
  • the adjustable throttle device can be statically adjustable, that is, over a plurality of working cycles away have a constant setting.
  • adjustable throttle device changes between substantially throttle-free time intervals and throttle-effective time intervals.
  • the throttle-effective time intervals can extend over less than one operating cycle of the reciprocating compressor or over several working cycles.
  • the throttle-free intervals extend over several cycles in order to affect the compressor performance as little as possible.
  • a first embodiment of a reciprocating compressor according to the invention for refrigerants shown in FIG Fig. 1 and 2 includes a crankcase 10 in which a crank drive 12 is provided and which forms a collection space 14 for lubricant 16, for example oil, which collects in the plenum 14 in the lubrication of the reciprocating compressor and forms a lubricant bath 18, the surface mirror 20 depending on Amount of the lubricant 16 in the lubricant bath 18 varies.

  • valve plate 30 On a cylinder chamber 26 opposite side of the valve plate 30 also a valve plate 30 cross-cylinder head 40 is provided, in which an inlet valve 32 reaching Sauggas Adjust 42 and a discharge valve 34 leading away pressure gas guide 44 are provided, the Sauggas Adjust 42 than from a suction 46th to the inlet valve 32 leading and, for example, predominantly directly above the valve plate 30 extending channel 48 is formed.
  • refrigerant to be compressed is supplied to the inlet valve 32 in the valve plate 30 via the suction gas guide 42 in the valve plate 30, namely, when the reciprocating piston 24 performs a suction movement, or the refrigerant in the suction gas guide 42 remains substantially flowless, namely when the reciprocating piston 24 performs a compression movement and compresses the refrigerant in the cylinder 26 and finally discharges via the discharge valve 34 into the pressurized gas guide 44.
  • the suction gas guide 42 is provided in the first embodiment with a nozzle 50 in which an acceleration of a suction gas stream 52 takes place before reaching the inlet valve 32.
  • a region 54 of reduced pressure occurs in which a pressure P1 can be reached that is below a pressure P2 in the crankcase 10.
  • an outlet opening 56 of a lubricant suction channel 60 designated as a whole, whose inlet opening 62 is arranged in the collecting space 14 of the crankcase 10, at a distance A from a bottom 64 of the collecting space 14, so that only through the inlet opening 62 as long as lubricant 16 can be sucked in until, as in Fig. 2 represented, the surface mirror 20 of the lubricant bath 18 at the level of the inlet opening 62 is.
  • the lubricant suction channel 60 is formed as a tube 66 which extends from the region 54 in the nozzle 50 to the inlet opening 62 and defined by the position of the inlet opening 62, the position of the surface mirror 20 of the lubricant 18, in which just a suction of lubricant is possible via the lubricant suction channel 60, while with further lowering of the surface mirror 20 no more suction of lubricant is possible.
  • the sucked into the nozzle 50 lubricant is supplied through the suction gas flow 52 via the inlet valve 32 of the cylinder chamber 26 and ejected from this again with the compressed refrigerant via the outlet valve 34 and thus discharged via the compressed gas guide 44, for example, conveyed with the pressurized gas to the next refrigerant compressor.
  • FIG Fig. 3 In a second embodiment of a reciprocating compressor according to the invention, shown in FIG Fig. 3 , All those parts which are identical to those of the first embodiment, provided with the same reference numerals, so that with respect to the description of which reference may be made in full to the comments on the first embodiment.
  • the lubricant suction channel 60 ' is not formed by a tube 66, but molded into the crankcase 10, such as a wall portion 70 thereof, such that the lubricant suction passage 60' in the wall portion 70 extends to the inlet port 62 also has an aperture 72 the valve plate 30 passes through and finally passes through an opening 74 of the nozzle 50, which extends to the outlet opening 56 in the nozzle 50.
  • FIG Fig. 4 In a third embodiment of a reciprocating compressor according to the invention, shown in FIG Fig. 4 are also those parts which are identical to those of the first or second embodiment, provided with the same reference numerals, so that the description thereof can be fully incorporated by reference.
  • the lubricant suction channel 60 extends in the tube 66, from the inlet opening 62 to an outlet opening 56 ', which in this embodiment lies in the region on a side of the valve plate 30 facing the suction gas guide 42, so that the outlet opening 56'. immediately adjacent to the provided in the cylinder head 40 channel 48.
  • a throttling device Aperture 80 is provided, which, when the reciprocating piston 24 performs an intake movement enlarging the cylinder chamber 26, leads to a pressure drop downstream of the orifice 80, so that the static pressure P 1 in the region 54 'between the orifice 80 and the inlet valve 32 during the suction movement 24 falls short term and thus a static pressure P 1 is at least temporarily set, which is lower than the pressure P 2 in the crankcase 10, in particular in the collecting space 14, so that during this time during which the static pressure P 1 is lower than the static pressure P 2 lubricant is then sucked out of the collecting space 14 via the lubricant suction channel 60, if the surface mirror 20 is above the inlet opening 62.

  • the outlet opening 56 is located on the valve plate 30 and in the area 54 ', which is located between an adjustable throttle device 90 and the inlet valve 32.
  • the throttle device 90 in this case comprises a passage 92, which is adjustable with an adjustable throttle valve 94, for example a pivotable about an axis 96 throttle valve 94, with respect to its throttling action for the suction gas stream 52, wherein, for example, an actuator 98 is provided.
  • This solution has the advantage that the adjustability of the throttle valve 94 by means of the actuator 98 according to the operating conditions of the reciprocating compressor, the periods at which the static pressure P 1 in the channel 48 is lower than the static pressure P 2 in the crankcase 10, in particular in the plenum 14 thereof, in each case in adaptation to the suction gas stream 52 is adjustable.
  • the variant of the third embodiment described above thus provides that the setting of the throttle valve 94 remains constant over a plurality of working cycles and thus the adjustment can be made so that at least temporarily, the static pressure P1 drops so far that a suction of lubricant 16 via the lubricant suction channel 60 takes place.
