US Patent:

54620660, Oct 31, 1995

Filed:

Feb 10, 1994

Appl. No.:

8/196009

Inventors:

David T. Snyder - Fair Oaks CA

International Classification:

A61F 537

US Classification:

128848

Abstract:

An anti-snore device, which includes a U-shaped thermoplastic mouthpiece, moldable to fit the jaw definition of the wearer which device has a generally H-shaped cross section, with rearwardly diminishing elevations of the outer and inner vertical walls, both above and below the base to which these walls are attached. The outer wall features front facing opposed upper concave and lower convex areas. The device also includes a downwardly extending flange which extends into the lingual or tongue side of the teeth vestibule of the user to maintain the lower jaw in a forward posture. An optional removable handle of similar thermoplastic material to aid the custom molding process for the fit to the wearer may be employed.

Inventors:

David T. Snyder - Fair Oaks CA

International Classification:

F02M 5300
F02M 3100

US Classification:

123557

Abstract:

A heater valve for a diesel fuel system for a vehicle having a main body portion with a fuel inlet and a fuel outlet adapted to be coupled to the vehicle fuel system. A fuel inlet line and a fuel outlet line from the valve are adapted to be coupled to a heat exchanger. A fuel distribution chamber in the valve is in fluid communication with the fuel inlet and the fuel outlet line and a fuel mixing chamber in the valve is in fluid communication with the fuel inlet line and the fuel outlet. A port opens into the mixing chamber and a spring bias valve in the mixing chamber has a restrictor normally restricting the size of the port opening with a valve shaft extending through an opening in a partition wall into the distribution chamber into engagement with a calibrator. A temperature sensor is associated with the valve for sensing the temperature of fuel in the mixing chamber and moving the valve to open both the port and the opening in the partition wall to allow fuel to flow into the mixing chamber from the distribution chamber.
