Definitions

  • the invention relates to a hydraulic system for a ship according to the preamble of claim 1.
  • Known hydraulic systems therefore comprise two hydraulic systems.
  • the first hydraulic system for the transmission is for the Gear lubrication and for the operation of the usual provided as a multi-plate clutch gear coupling.
  • a separate one is used to operate the variable pitch propeller second hydraulic system used.
  • variable displacement pumps In contrast, one has so far for the second hydraulic system with the second associated oil circuit for operating the second adjustment valve of the variable pitch propeller as an oil pump a variable displacement pump is used.
  • Variable displacement pumps generally considered optimal because of their mode of action Pump oil in the oil circuit only if the variable valve must be operated for the variable pitch propeller. in the Idle state, i.e. when the adjustment valve is not actuated there is no oil production, even though the variable pump is continuously driven by the gearbox via a PTO shaft.
  • the variable pitch propeller or the corresponding second variable valve has been operated comparatively rarely so far the use of a variable displacement pump to save energy enforced for the second oil circuit.
  • the invention is based, while maintaining the task a common oil sump a hydraulic system for a Specify ship, which despite air bubbles in the oil circuit enables safe actuation of the ship's propeller.
  • the invention comes for the first time Oil feed pump of the second oil circuit for the variable pitch propeller assigned variable valve a constant pump for Use as in the first oil circuit for actuation the gear coupling is provided.
  • the invention goes assume that the operation of a constant pump to promote a constant amount of oil due to air bubbles in the oil in the Practice is only negligibly influenced.
  • the second Parking valve operated with the help of control oil, this Control oil via a control oil line to the first oil circuit is removed.
  • the invention surprisingly solves the contradiction which is that, on the one hand, the previous one for energy reasons Use of a variable displacement pump for the second variable valve was sensible, and that on the other hand the use of a Constant pump due to the influence of air bubbles in the oil allows the pump to function safely, although the Constant pump is continuously in operation and continuously oil promotes that, however, for reasons of energy saving Constant pump for the variable valve of the variable pitch propeller doesn't make sense.
  • the invention provides another feature before that the control oil through a control oil line from the first Oil circuit is removed. It is assumed that a fine filter is provided in the first oil circuit, and that thus very clean oil is conveyed in the first oil circuit becomes. This clean oil ensures safe and secure reliable control or activation of the second adjustment valve for the variable pitch propeller.
  • the hydraulic system for a ship shown in Fig. 1 is for actuating the gear coupling 20 of a gear 18 and for adjusting a driven by the transmission 18 Variable propeller 17 is provided.
  • the one driving the transmission 18 Ship engine is for reasons of clarity Drawing not shown.
  • a first hydraulic system is used to actuate the transmission clutch 20 provided which a constant pump 1, a Includes fine filter 2 and an oil cooler 3, on which a pressure relief valve 4 connects, whereby a first Oil circuit is formed.
  • a first Oil circuit In this oil circuit one becomes in the housing of the gear 18 oil sump 12 continuously Oil extracted.
  • the gearbox clutch is actuated via a connected to the oil production circuit Switch valve 5, which is designed as a black / white valve is. This flows when the switching valve is closed Oil delivered by the constant pump 1 via the pressure relief valve 4 back, while with the switching valve 5 and a smaller proportion when the switching valve is actuated of the oil flows into the clutch 20.
  • the pressure relief valve 4 is that for the gear coupling 20 required pressure set, and by actuation of the switching valve 5 becomes the transmission clutch on or off.
  • the electrical control of the Switching valve 5 is carried out by an electronic control device 11, through which the switching valve 5 for actuation can be activated.
  • the Hydraulic system a second hydraulic system with a second Oil circuit for the actuation of the variable pitch propeller 17.
  • this second oil circuit includes an oil pump Constant pump 6, a coarse filter 7, and a controllable and adjustable pressure relief valve 8.
  • Parallel to this Pressure relief valve 8 is an adjusting valve special valve arrangement in the form of a proportional directional valve 9.
  • a first oil line leads from the proportional directional valve 9 13 and a second oil line 14 to an adjusting cylinder 10.
  • This has a rod side in a manner known per se 15 and a piston side 16 and serves to adjust the Variable pitch propeller 17.
  • Fig. 2 shows the proportional directional control valve 9 in its neutral position.
  • the pressure relief valve 8 is on such Value set that the constant pump 6 (see Fig. 1) Oil extracted from the common oil sump 12 the least resistance via the oil line 21 (Pressure line) and via the tank line T back into the oil sump 12 takes. In the neutral position there is therefore an off Energy-efficient advantageous simple unpressurized circulation of the Oil.
  • Fig. 3 shows the proportional directional control valve 9 in a first Working position for actuating the adjusting cylinder 10 (cf. Fig. 1) on lines 13 and 14.
  • the proportional directional valve 9 initially via the electronic Control device 11 and via the control oil line X in the Actuated that the working position shown in Fig. 3 is taken. In this working position it is before described pressure-free circulation of the oil canceled.
  • the oil from the constant pump 6 is rather via the line 21 and via line 13 to the rod side 15 of the adjusting cylinder 10 headed.
  • the oil pressure rises as a result to the value set on the pressure relief valve 8. That displaced on the piston side 16 of the adjusting cylinder 10 Oil flows through the second oil line 14 and through the permeable Proportional directional control valve 9 and via line T in the common oil sump 12 back, so that with the help of the adjusting cylinder 10 of the variable pitch propeller 17 in a first Direction can be adjusted.
