ABSTRACT:
Valve seat structure for an automotive thermostatic fluid control valve device which is adapted to be positioned within a coolant fluid conduit system of an automotive engine. The valve seat structure has a rigid fluid flow control member which includes a cylindrical wall which forms a fluid flow passage. The rigid fluid flow control member also has an annular base which encompasses the cylindrical wall. An elastomeric sealing member resiliently encompasses the cylindrical wall. The elastomeric sealing member has an abutment portion and a clamping portion. Preferably, the abutment portion and the clamping portion are separated by a shoulder. A rigid clamping member has a clamping portion which is in engagement with the clamping portion of the elastomeric sealing member and is adapted to be clampingly engaged by a part of the coolant fluid conduit system. The rigid clamping member also has a shoulder portion which engages the shoulder of the elastomeric sealing member. The valve seat structure is adapted to be clamped between two portions of the coolant fluid conduit to maintain the position of the valve seat structure within the coolant fluid conduit. Thus, the rigid clamping member firmly retains the elastomeric sealing member with respect to the fluid flow control member. The abutment portion of the elastomeric sealing member is also engageable by a movable valve member to control fluid flow through the fluid flow passage.
