3. Structure and Working Principle
Refer to figure 1 .
1、 Oil pump is a hand and variable plunger pump , the motor drives pump shaft to rotate through elasticity shaft coupling, the absorbing oil cavity forms gradually when plunger pump running and oil flows into it under atmosphere pressure effect, because of reciprocating motion of plunger pump and oil blow out then into oil circuit , at the same time plunger pump adjusts flow capacity.
2、 YF-B20 control valve is a high pressure overflow valve , the rated pressure is set as 16Mpa .when work pressure is over than 16MPa, the valve opens and a part of oil returns to tank that system pressure will not over set value for sure system safe.
