  • Publication number: 20090312674
    Abstract: A compact and lightweight electromagnetic valve with a check valve is provided. In the electromagnetic valve, a plunger 16 is moved toward an end wall 22 of a housing of the electromagnetic valve by applying a voltage to a solenoid 14. Then, an annular valve seat engaging portion 64 of a valve member 48 attached to the plunger is urged against a valve seat around a fluid outlet 26 formed in the end wall 22 while being elastically deformed, thereby closing the fluid outlet 26. At the same time, a valve pressing member 46 attached to the plunger is separated from a valve member 52 disposed at a fluid opening 24 of an end wall 20 of the housing. Thus, the valve member 52 disposed at the fluid inlet 24 of the housing functions as a check valve to allow pressurized air to flow in from a pump. In a case where a voltage is not applied to the solenoid 14, the plunger 16 is biased toward the fluid inlet by means of a compression spring 60.
