Part and oil distribution casing.The plunger assembly includes the cylinder body with transmission shaft coaxial arrangement, and the cylinder body is along its axis direction
Several cylinder holes are uniformly distributed, cylinder sleeve is equipped in each cylinder holes, the plunger being slidably matched with the cylinder sleeve is equipped in each cylinder sleeve, it is described
The bulb of plunger first end is fixed on swash plate by piston shoes, and second end is inserted into the cylinder sleeve.
The cylinder sleeve inner sidewall is equipped with suction passage, and the lateral wall of the plunger is equipped with oil storage tank.The suction passage
First port is located at the first side of the oil storage tank, and is connected with the oil storage tank.The second port of the suction passage with
The second end of the plunger is connected to the operating room that cylinder sleeve inner sidewall is constituted.
Second side of the oil storage tank is equipped with the oil return hole being connected to the plunger.
Preferably, the second end of the plunger is equipped with sealing ring.
Preferably, the second port of the suction passage is obliquely installed to the side of the second end far from the plunger.
Preferably, the oil return hole is obliquely installed to the second end of the plunger.
The technical solution of the utility model on the inner sidewall of cylinder sleeve by being arranged suction passage, and in the lateral wall of plunger
Upper setting oil storage tank pulls out plunger when swash plate is rotated out of cylinder sleeve, is that indoor partially liq sucks in oil storage tank by work,
Reduce the indoor oil pressure of work, to quickly improve plunger response speed in new liquid adsorption operating room.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
