Abstract: A combination fuel pressure regulator and fuel filter apparatus for vehicle fuel systems has a fuel supply tank with a fuel pump therein for puming fuel to a fuel supply rail having fuel injectors attached thereto. A fuel filter is operably disposed between an inlet supply tube and a fluid outlet tube for filtering impurities from fuel passing therethrough. A valve in fluid communication with the inlet supply tube is provided with a regulator for causing flow to be short circuited back into the fuel supply tank when the pressure in the fluid outlet exceeds a predetermined level. The valve is biased to a closed position and will remain closed as long as the pressure on the clean side of the filter is below the predetermined pressure whereby all of the fuel in the inlet supply tube will pass through the filter.

Abstract: A pressure regulator having a housing with a chamber disposed therein. A diaphragm is sealingly connected around the inner periphery of the housing for dividing the chamber into two parts. A first port is fluidly connected to a first part of the chamber and is adapted to be attached to a fuel return line. A second port is fluidly connected to the first part of the chamber and is adapted to be fluidly attached to a fuel rail having fuel injectors attached thereto. A third port is fluidly connected to the second part of the chamber and is adapted to be fluidly connected to an intake manifold of an internal combustion engine. A resilient flat washer is attached around the outer periphery thereof to the housing, adjacent to the first part. An elongated valve member is disposed in the first part of the chamber and has one end thereof adapted to be selectively and sealingly received within the opening in the washer.

Abstract: An actuator mechanism for an aerosol container of a type including a chamber for holding fluid under pressure has an outlet opening disposed in the container and a valve attached to the container for controlling the flow of fluid from the opening. The actuator mechanism includes a cap having an outlet opening on one side thereof, which cap is attached to the container adjacent to the outlet opening of the container. An actuation structure is provided for selectively causing fluid to be dispensed from said chamber and out through the outlet opening of the cap upon reciprocation of the actuation structure with respect to the container. The actuation structure includes a nozzle for permitting fluid to be sprayed therethrough. The nozzle is aligned with the outlet opening in the cap. A stem is operatively attached to the nozzle and to the valve for communicating fluid from the container chamber, through the valve and the nozzle when the valve is open.

Abstract: This invention relates to check valve assemblies in general, and more specifically to an easy opening fuel line check valve assembly, wherein a cage structure which supports a free floating ball valve allows a relatively weak spring to be employed for the closing bias while avoiding the buckling problem normally associated with weak spring elements in similar valve assemblies.

Abstract: A valve for use in a vehicle fuel line between a fuel tank and a fuel pump for preventing fluid from flowing from the fuel tank to the carburetor of an engine when the fuel pump is not functioning and for allowing such fuel to pass through the fuel line to the fuel pump and carburetor when the fuel pump is in operation. A valve assembly within a chamber of the valve is biased to a closed position, but is movable to an open position in response to a suction effect from the fuel pump. The valve assembly includes a novel structure for insuring a positive seal when the valve is closed.

Abstract: A valve of a type used for preventing fuel line leaks which occur when automobiles or trucks roll over. The valve is used in conjunction with a vehicle fuel system, preferably in a vapor vent line which vents fuel vapors from the fuel tank, so that if the vehicle rolls over or tilts in one direction by more than a predetermined amount, the valve will close. A ball disposed in a conical recess within the valve body serves as a gravity actuator for a reciprocating valve member. A novel structure of a valve member of a particular configuration in combination with the novel configuration of the interior of the valve housing allows the valve member to be self-cleaning due to vibrations caused by vehicular travel; and yet, the valve provides a positive sealing function upon tipping or tilting thereof by a predetermined amount or more.
