Flow Actuating Switching Device
US Patent:
4365125, Dec 21, 1982
Filed:
Mar 22, 1982
Appl. No.:
6/360203
Inventors:
George D. Keller - Philadelphia PA
Assignee:
Beta, B.V. - The Hague
International Classification:
H01H 3538
US Classification:
200 819M
Abstract:
A fluid actuated switching system is disclosed which comprises a fluid actuated poppet mounted in a fluid passageway for movement from a first position in the absence of fluid flow to a second position in response to a predetermined fluid flow. An elongated permanent magnet element is mounted on the poppet for movement along the axis of movement of the poppet. A second magnet element is positioned exteriorly of the fluid passageway adjacent the first magnet element. The two elongated magnet elements are polarized so that like poles are adjacent to one another and repel the two elements when the flow actuated poppet is in the first position and attract one another when the flow actuated poppet is in the second position, thereby moving the second magnet element with a snap action from one position to the other. The second magnet element actuates an electrical or pneumatic switch. As disclosed, the flow actuated poppet moves along an axis which is perpendicular to the axes of the inlet and outlet ports of its housing.
