Claims

[Scope of utility model registration request]

A valve body having a negative pressure input port, an atmospheric input port, and an output port, a cup-shaped plunger disposed within the body, a cup-shaped plunger that is fitted into the mouth of the plunger and fixed integrally, and a , a non-magnetic sheet member to which an inner peripheral part of a diaphragm whose outer peripheral part is fixed to the body and has an opening on a side surface; a negative pressure input port disposed in the plunger and formed in the valve body; a poppet valve biased by a spring so as to come into contact with the valve'seat; a solenoid portion disposed coaxially with the plunger and controlled to excite in accordance with an electric signal;
an adjusting core disposed opposite to the plunger at the axial center of the solenoid portion so as to be movable in the axial direction and adjusting an initial gap length with the plunger; fixing the body and the solenoid portion; and fixing the body and the solenoid portion, and the plunger and the solenoid. and a yoke member that also serves as a bracket constituting a magnetic circuit of the core, the plunger is press-molded and has an atmospheric hole communicating with the atmospheric input port in the outer peripheral part,
The non-magnetic sheet member is also press-formed, has a flange portion on its side surface, the inner peripheral portion of the diaphragm is sewn and fixed to the outer peripheral surface, and the side surface can come into contact with the valve seat surface of the poppet valve. An electromagnetic negative pressure control valve, characterized in that the poppet valve is made of a non-metallic molded product and is urged to abut against the valve seat with a relatively light force.
