US Patent:

52172007, Jun 8, 1993
Filed:

Dec 3, 1991
Appl. No.:

7/801879
Inventors:

Peter G. Hutchings - Nashua NH
Matthew E. Leinheiser - Mishawaka IN
John W. Mezas - Granger IN
Assignee:

South Bend Controls, Inc. - South Bend IN
International Classification:

F16K 3106
US Classification:

251 86
Abstract:

A laminar flow control valve having a unitary housing, wherein the valve housing is coupled to a housing for an electrically powered solenoid device. The poppet is loosely secured to the valve stem by use of a magnet, which permits lateral movement between the poppet and the valve stem. In the preferred embodiment, a hemispherical poppet is mounted to the stem of the operating mechanism by a magnet which is fixedly secured to the stem, permitting lateral movement of the poppet to ensure self-alignment with the valve seat upon closing of the valve. An alternative embodiment utilizes conical surfaces of the valve seat and poppet.
