Embodiment Construction
[0019] The specific embodiments of the present invention will be further described in conjunction with the accompanying drawings, and the embodiments are used to illustrate the present invention, but not to limit it in any way.
[0020] The invention is a multifunctional valve group which combines a plunger type oil distribution check valve, a pressure regulating valve, a safety valve, a reversing slide valve, a pressure gauge and a pressure sensor. The structure and functions are introduced as follows:
[0021] 1. Oil distribution check valve—the two plungers alternately supply oil. In order to ensure the vacuum degree of the oil suction chamber and prevent the oil supply pressure from failing, the present invention changes the oil distribution check valve 2 from spring reset to forced oil pressure. Reset structure. That is to say, when one plunger discharges oil, the check valve at the outlet of the other plunger is forcibly closed (see figure 1 , 2 ). The combination of...
