Electromechanical Valve

摘要

An electromechanical valve includes, in a housing, a core of magnetic material surrounded by a coil to be supplied with excitation current, a valve seat attached to the housing with a space to the core, at least one outlet port in the valve seat and at least one inlet port communicating via the space, and a valve washer of magnetic material suspended in the space to close the outlet port in absence of excitation current to the coil, the valve washer cooperating with the core to open/close the outlet port when excitation current is supplied to the coil.

1. An electromechanical valve, comprising in a housing:
a core of magnetic material having a centrally extending portion surrounded by a coil to be supplied with excitation current; a valve seat attached to the housing with a space to the core; at least one centrally located outlet port in the valve seat and at least one inlet port communicating via the space; and a valve washer of magnetic material suspended in the space to close the outlet port in absence of excitation current to the coil, the valve washer cooperating with the core to open the outlet port when excitation current is supplied to the coil, and the valve washer being formed by multiple layers of electromagnetic material providing a spring force when the valve washer is compressed.
