  • Patent number: 5971288
    Abstract: A thermostatic control valve has an expansion composition held in a cavity thereof. The composition contains electrical conductor particles dispersed throughout an electrical isolator. The particles conduct electrical current through the isolator when the electrical isolator has a volumetric size that is less than a predetermined expanded volume. When the isolator expands to the predetermined expanded volume, the distance between the particles is increased to the extend that the electrical current cannot be conducted.

  • Patent number: 5410991
    Abstract: An apparatus is provided for filling an engine cooling system with coolant fluid and for controlling fluid flow through the cooling system using three dimensional weirs in response to changes of an engine cooling system temperature. The apparatus includes a fill housing having an inlet section, an outlet section, and a fill section configured to receive a cap thereon. The inlet section is formed to include a valve seat and a flange for coupling the fill housing to an engine. The apparatus also includes a thermostat and means for coupling the thermostat to the flange to hold the thermostat within the inlet section beneath an outer surface of the flange. The fill housing is formed to include a venturi portion located between the inlet section and the outlet section to provide a pressure drop in the fill housing as fluid flows through the fill housing. The venturi portion is located adjacent the fill section to subject the fill section to the pressure drop as fluid flows through the fill housing.

  • Patent number: 4763834
    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.

  • Patent number: 4587931
    Abstract: A pressure compensated temperature switch for the protection of an internal combustion engine or the like. The switch unit includes a housing, a portion of which is positioned within a passage in the cooling system of the internal combustion engine. Within the housing is a pressure sensitive member. The pressure sensitive member senses both the temperature and the pressure of the coolant fluid in the coolant system of the internal combustion engine. A visual and/or audible alarm device which is connected to a switch unit of this invention, thus operates when temperature conditions exist within an engine which are harmful to the engine.

  • Patent number: 4562953
    Abstract: Valve seat structure for an automotive thermostatic fluid control valve device. The valve seat structure comprises a rigid fluid flow control member which includes a cylindrical wall which forms a fluid flow passage and an annular base which encompasses the cylindrical wall. An elastomeric sealing member or engagement member resiliently encompasses the cylindrical wall and is clamped between two portions of a fluid conduit to position the valve seat structure within the fluid conduit. The elastomeric sealing member is also engageable by a movable valve member to control fluid flow through the fluid flow passage. The cylindrical wall extends beyond the elastomeric sealing member and protects the elastomeric sealing member against the forces of fluid flow.
