Definitions

  • the invention relates to a compressor according to the preamble of the claim 1.
  • compressors are regulated by pressure regulating valves (governor).
  • pressure regulating valves here will the air flow delivered by the continuously running compressor in the idling phase throttled by a device on the suction valve of the compressor or by venting devices discharged into the atmosphere at the pressure control valves.
  • This idle phase energy consumed by the compressor is pure energy loss.
  • the share of this energy loss in the total energy consumption of the compressor is not inconsiderable, because in vehicles the switch-on time is ED, among them the time during which the compressor pumps compressed air into the system is rarely understood over 30% of the entire term. Stopping the compressor, e.g. B. via a shut-off clutch, is not practiced because the torque curve, especially the torque peaks, very large and expensive couplings required do.
  • the object of the invention is, in particular for to represent the compressed air generation in motor vehicles, which compressor is not subject to the aforementioned disadvantages and problems, and which at compact design, but can be manufactured at a comparable price, like compressors today's construction.
  • the compressor is characterized by a largely oil-free run, since by the stripping and sealing elements acting on the piston rods are very effective Sealing between engine and compressor part, d. H. compared to that the back of the piston located suction chamber is formed.
  • the axial piston compressor shown in Figures 1 and 2 in the form of a swash plate compressor has an oil-lubricated engine 1, which essentially from a swash plate 5 and hemispheres mounted on a drive shaft 3 7 in 9 pans.
  • the engine 1 of known mode of operation is used to make 3 straight-line movements when the drive shaft rotates to reach the piston rods 13 carrying the pistons 11.
  • Warehousing the piston rods 13 take place in bearing bores 15 on the oil-lubricated engine side.
  • the bearing bores 15 extend on a pitch circle at an angular distance to each other parallel to the longitudinal axis of the compressor by a middle Housing section 17, on which the piston facing oil-stripping sealing elements 19 are provided.
  • the ones on the back of the pistons Chambers 21 are through an annular space 22 ( Figure 1) to a common suction space connected, in which a suction port opens.
  • the pistons 11 are equipped with piston rings 23 suitable for oil-free dry running and move in the cylinder bores preferably without contact.
  • This suction valve provides the connection between the piston during the suction stroke Suction chamber and pressure chamber 24 forth, the valve in accordance with FIG left-hand movement of the individual piston opens such that air through the Suction port and the interconnected chambers 21 in the pressure chamber 24 arrives and with subsequent movement directed to the right according to FIG closing suction valve 25 via the pressure valve shown in the sectional view 29 and an annular pressure chamber 30 are pushed into the pressure connection 31 becomes.
  • the cylinder head 33 of the pressure valve 29 Cool the compressor in an optimal way, since more cooling surface is available.
  • the cooling oil and Lubricating oil circuit identical, the pressure oil via the inlet 35 from the Lubricant circuit of the vehicle engine is fed to the compressor.
  • the oil initially flows for cooling via the annular space 37 and the connection 39 through the cylinder head into the central oil chamber 41; this is through the front End of the drive shaft 3 of the compressor limited. Extends through the drive shaft centrally an oil hole 43, from which at different positions Branch off branch bores 45.
  • Branch bore is lubricated as shown, the right end of the drive shaft 3; Oil is drilled into the interior of the engine via further branch holes initiated. Inside the engine, the oil is used to lubricate all those with friction Divide and leave the compressor through an outlet 47, which communicates with the interior of the engine. In the area of lubrication A seal 48 is provided on the right-hand end of the drive shaft 3, which prevents oil from entering the suction chambers. Passes through the outlet 47 the oil back into the lubricant circuit of the vehicle engine.
  • cooling oil 41 is along the outer circumference of the housing or channels placed in the housing wall passed into the engine 1. In this case, the oil chamber 41 is opposite closed the facing end of the drive shaft 3.
  • the very favorable torque curve of the compressor described above makes use of a compact, inexpensive shutdown clutch possible. It is possible to use the shut-off clutch, here as an electromagnetic clutch 49 shown to accommodate space-saving in the interior of the compressor.
  • the Swash plate 5 is rotatably mounted on the drive shaft 3 and is at Excitation of the magnet from a magnetic disk fixedly attached to the drive shaft 3 51 driven.
  • the magnetic disk 51 takes frictional engagement one with the swash plate 5 e.g. Drive plate connected by screws 52 with.
  • the magnet is de-energized, the engagement between the drive plate is released and magnetic disc, so that the drive shaft 3 runs empty and the compressor pistons are switched off.
  • the control with a pneumatically switched clutch is of a similar design possible.
  • the drive shaft and the swash plate are separated, it is possible to produce the swash plate from an inexpensive and well lubricated material, such as. B. Al cast.
