Multiple-way valve

摘要

A multiple-way valve having a housing forming a chamber with which two spaced apart fluid ports communicate. An actuator is accommodated in the chamber and has two spaced apart closures which are operable to open and close the ports. The actuator is biased to a position in which one port is closed and the other port is open but the actuator may be rocked in response to energization of an electromagnet to a position in which the one port is closed and the other port open. In moving from either position to the other the actuator rocks first about one fulcrum and then about a second fulcrum. The two fulcrums are so located as to facilitate initial movement of the actuator from either of its positions thereby minimizing the power required to be applied by the electromagnet.
