Fluid Proportioning Valve And Method
US Patent:
6039065, Mar 21, 2000
Filed:
Mar 8, 1999
Appl. No.:
9/264417
Inventors:
John P. Gagliardo - Shrewsbury MA
Assignee:
Regal Products, Inc. - Shrewsbury MA
International Classification:
F16K 510
US Classification:
137 3
Abstract:
A fluid proportioning valve meters a flow of secondary fluid into a flow of primary fluid in a predetermined, controllable proportion of secondary fluid to primary fluid and in a predetermined, controlled volume flow of secondary fluid responsive to volume flow of primary fluid. The fluid proportioning valve includes: a housing defining a conduit in operation for flow of secondary fluid from an inlet in communication with a source of secondary fluid towards an outlet in communication with a source of primary fluid; a first valve element disposed within the housing and defining a first valve opening between inlet and outlet; and a second valve element disposed within the housing and defining a second valve opening between inlet and outlet. The first and second valve elements are mounted for relative movement in first and second degrees of motion, the first and second valve openings being in overlapping relationship in at least some position of the first and second valve elements, to permit flow of secondary fluid from the inlet toward the outlet.
