An electromagnetic flow control valve assembly includes a valve body having first and second ports and a valve member for controlling fluid communication between said first and second ports. An annular diaphragm is connected at its inner periphery to the valve member and at its outer periphery to the valve body so as to define with said valve body first and second chambers. The first chamber is in continuous fluid communication with the first port through a passage in the valve member while the second chamber is in continuous communication with the second port. The area of the diaphragm subjected to fluid pressure within the second chamber being equal to the effective area of the valve member subjected to fluid pressure within the second chamber to thereby offset the force of fluid pressure acting on the valve member.

DETAILED DESCRIPTION OF THE INVENTION An electromagnetic flow control valve assembly 10 is comprised of metal bodies 12 and 13 which are secured to each other by means of a member 11.
A cover 16 of resin material is secured to the body 12 through a gasket seal 14 by bolts 15 and a cover 17 of metal material is secured to the body 13 by bolts, not shown.
A pair of magnetic members 20 and 21 are located within the body 12 and are secured to each other by any suitable means.
A non-magnetic bobbin 19 is positioned about the bodies 20 and 21 and a solenoid coil 18 is disposed on the bobbin 19.
A rod 25 is guided for axial sliding movement within members 20 and 21 by means of bearings 22 and 23.
The bearing 22 is held in position by means of an annular member 24 secured to one end of member 20 about the rod 25.
A magnetic member 27 is secured to the right end of rod 25 and is biased to the left by means of spring 26 located between the magnetic member 27 and the cover 16.
While both electrical leads for the solenoid coil 18 are connected to terminals on the end cover 16, only one lead 29 is shown which passes through an aperture in the gasket 14 and a grommet-type terminal 28 for connection to the electrical supply wire 30 which passes through a resilient protective sleeve 31 on the cover 16.
A sealing compound 32 completely seals the terminal 28.
The terminals may be connected to a computer which receives an electrical signal from an oxygen sensor which is positioned within an engine exhaust manifold and therefore the electric current flow to the solenoid coil 18 is determined by the computer.
The body 12, magnetic members 20,21 and 27 comprise a magnetic circuit to generate a magnetic force in proportion to the electric current supplied to the solenoid coil 18 and accordingly, rod 25 is moved to the left in proportion to the applied current flow.
The left end of the rod 25 is secured to a valve member 34 having a resilient valve portion 33 secured thereto.
The valve member 34 is comprised of a first portion 35 having a substantially conical surface on the side thereof connected to the rod 25 and a second portion 36 on which the valve portion 33 is secured
