Definitions
- the flow path switching unit is provided with an urging means for urging the valve shaft toward the electromagnetic unit, and the valve unit is driven by the electromagnetic unit. If not, the urging force of the urging means releases the contact with the flow path switching unit to open the throttle, and the communication between the output port and the discharge port is blocked, and the electromagnetic unit is driven. Then, until the flow path switching unit comes into contact with the valve body, the second flow path is gradually blocked in conjunction with the flow path switching unit while maintaining the opening of the throttle by the biasing force of the biasing means.
- the case 31, the first core 34, the second core 35, and the plunger 36 are all formed of a ferromagnetic material such as high-purity iron, and the end surface of the cylindrical portion 34 b of the first core 34 and the second core 34 are formed.
- the space between the end surface of the core 35 is formed so as to function as a nonmagnetic material.
- nonmagnetic metals such as stainless steel and brass.
- the pressure regulating valve portion 40 is inserted into a substantially cylindrical hollow sleeve 42 having one end attached to the case 31 and the first core 34 of the solenoid portion 30, and the inner space of the sleeve 42.
- a substantially cylindrical hollow member that divides the internal space of the sleeve 42 and flows the hydraulic oil flowing into the sleeve 42 into the hollow member, the outer peripheral surface of the hollow member, and the inner peripheral surface of the sleeve 42.
- a flow path switching unit 60 that forms a flow path that circulates between them and switches the flow path, and is inserted into the flow path switching unit 60 in contact with the tip of the plunger 36 to open and close the valve together with the flow path switching unit 60
