Embodiment 1
[0023] exist figure 1 In the shown embodiment, the improved plunger type fluid pump and motor include a cylinder body 3 with a fluid chamber 2 mounted on a shaft 1, a plurality of plunger assemblies 4 sliding in the cylinder body 3, and the plunger assembly The variable plate 5 in contact with 4 and the variable mechanism 6 connected with the variable plate 5, the plunger type fluid pump and the motor are also provided with a plunger holding device 7 to keep the plunger assembly 4 separated from the variable plate 5 or to restore contact. The plunger holding device 7 is a hydraulic control device. The plunger holding device 7 includes a control chamber 8, a control valve 9 and a control fluid 10. The control valve 9 is a two-position three-way valve. The control fluid 10 is connected with the control chamber 8 through the control valve 9, and the control fluid 10 comes from an external low-pressure fluid. The plunger assembly 4 is in the form of a plunger shoe part, including...
