A manifold deck is formed with the valving channels and ports therein for connecting to the hydraulic circuits. A gasket is formed with solenoid valve mounting bosses and valving passages as a unitary member and is retained on the manifold deck by a retaining plate preferably stamped from sheet stock with clearance holes received over the valve mounting bosses and secured to the manifold deck over the gasket for sealing the gasket thereon. The valves are inserted in the bosses and retained by a preferably stamped bracket and the bracket, retaining plate and gasket secured to the manifold deck by common fasteners. A common electrical lead frame is received over the valve terminals for making electrical connection to the valves.

Abstract: A servo motor operated rotary air throttle has a driving member connected to the throttle shaft. The motor rotor is connected to the driving member in a lost motion connection. If the throttle is lodged due to ice formation, the motor rotor acquires rotary momentum relative to the driving member during the lost motion rotation and a projection on the rotor impacts the end of a slot in the driving member to impart a momentum pulse to the driving member and throttle shaft and dislodge the throttle.

Abstract: A pressure responsive relief valve is disposed in the tank vapor line to the engine inlet manifold and upstream of an electric flow control valve. The pressure responsive valve has a bleed orifice for providing limited flow for leak testing when the relief valve is closed; and, the relief valve is set for opening at a selected pressure differential to provide adequate vapor canister purge flow during engine operation. A differential pressure sensor is employed to read the pressure drop across the bleed orifice during leak testing and the flow determined from a lookup table for comparison with a threshold value to determine if leakage is present in the system.

Abstract: A vapor vent valve has an annular locking ring received thereover, with surfaces thereon engaging the valve for limited axial movement therebetween and preventing relative rotation therebetween. A fuel tank has an access opening with a slit formed therein. The valve is inserted in the access opening and the end of the locking ring engaged in the slit, rotation of the valve causes the locking ring to feed completely through the slit to the interior of the tank and engages the inner surface thereof while continuing to engage the valve to retain and seal the valve in the access opening. The valve, locking ring and a seal ring may be pre-assembled to form a subassembly capable of being installed and locked on the fuel tank as a unit without the need for tools or fasteners.
