ELECTROMAGNETIC ACTUATOR
Document Type and Number:
WIPO Patent Application WO/1982/001577
Kind Code:
A1
Abstract:
An electromagnetic actuator which controls the operation of a load such as a valve by utilizing the pressure of fluid driven by an electromagnetic pump. A driven member (17) is displaced by the pressure of the fluid fed from the first chamber (8) to the second chamber (9) by the pump (2), thereby opening, closing or proportionally controlling a valve (22) connected to the member (17), and the actuator can thus provide sufficiently large and effective operation for the load.
