Abstract

A three-way dual seat valve having a valve body including mutually spaced apart annular first and second valve seats. Reciprocally mounted with respect to the valve body is a dual-faced valve stem gate, wherein each gate face thereof is sealingly engageable with a respective valve seat in response to reciprocal movement of the valve stem gate effected via a leadscrew drive system.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of currently pending Serial No. 13 / 286,452 filed November 1, 2011. technical field [0003] The present invention relates to valves, including coolant valves commonly used in automotive applications. More specifically, the present invention relates to a reciprocating three-way double-seat valve. More specifically, the present invention relates to a lead screw drive system for providing valve actuation. Background technique [0004] Valves are ubiquitous in fluid flow systems to provide directional control of fluid flowing in the valves. A valve is used to open and close the direction of fluid flow, wherein the valve can function between a fully open state and a fully closed state, or can be progressive, wherein the open state is selectively between a fully open state and a fully closed state somewhere to meter fluid flow. The valve may be a two-way valve, controlling fluid...
