Abstract
A magnetically-actuated membrane valve for controlling and/or regulating the flow of a liquid medium is described which valve comprises a control membrane fixedly clamped in a valve housing, and an armature frictionally connected with the membrane, which armature is arranged on that side of the membrane which faces away from the exciting coil and from the magnet core of the solenoid, whereby the magnetic flux flows through the membrane, especially for the control of the flow of a liquid which serves as control means in a fuel injection system.
Claims22
A magnetically-actuated membrane valve for the control or regulation or both of the flow of a liquid medium comprising:
- a valve housing;
- a control membrane held in position in said housing;
- a solenoid coil and a magnetic core on one side of said membrane;
- and an armature on the other side thereof, in said housing, whereby the magnetic flux between the solenoid coil and armature passes through said membrane;
- and a valve seat obturated by said control membrane when said valve is closed, wherein said valve seat is located on the same side of said control membrane as said armature.
A magnetically-actuated membrane valve for the control or regulation or both of the flow of a liquid medium comprising:
- a valve housing;
- a control membrane held in position in said housing;
- a solenoid coil and a magnetic core on one side of said membrane;
- and an armature on the other side thereof, in said housing, whereby the magnetic flux between the solenoid coil and armature passes through said membrane wherein said housing comprises two chambers separated by said control membrane, one of said chambers communicating with an entry bore of the housing and the other of said chambers communicating with at least one discharge bore of the housing, said control membrane comprises throttle means, and said two chambers of said housing on both sides of said control membrane are in free communication with one another through said throttle means.
