<p>PROBLEM TO BE SOLVED: To provide a rotary swash plate type plunger pump that can be made more compact and more low-cost.SOLUTION: A rotary swash plate type plunger pump 1 includes: a liquid chamber communicating with a first port 40a formed to be open to the outside; a shaft 21 arranged in the liquid chamber 11 and supported rotatably; a disk-like swash plate 22a fixed to the shaft 21 to be inclined to a plane perpendicular to the axis 21a of the shaft 21; a magnet 23 fixed to an outer periphery of the swash plate 22 and constituting the rotor 20 of an electric motor; a stator 30; a plurality of cylinders 72 made open facing the liquid chamber 11; and a plunger 90 fitted to the cylinder 72 and also having one end in contact with the swash plate 22a and the other end partitioning off a pump chamber 74 in a cylinder 72. The pump chamber 74 and liquid chamber 11 communicate with each other through one of an inflow valve 80 and a discharge valve 60, and the pump chamber 74 and a second port 40b formed to be open to the outside communicate with each other through the other of the inflow valve 80 and discharge valve 60.</p> |
