Abstract: An automatic air tank drain is provided by forming a venturi induced suction at the tank outlet which draws liquid out of the tank as the tank air is exhausted past the venturi through a flexible hose positioned by a weight at the tank bottom.

Abstract: The engine starting system herein described controls an engine starting sequence which prevents start attempts when the engine is running and regulates the starting function within a control range of revolutions for efficient use of the available starting power either in the form of pressurized fluid from a tank or electrical discharge of a battery to effectively extend the efficient starting cycle of an engine.

Abstract: A drive pinion for an engine starting motor having a lead-in chamfer of the starter pin defined by a geometry formed by rotating the radial gear tooth involute form through 90 degrees across the end of the tooth. The radius and axis of rotation are selected such that the cam surface is full across the height of the tooth and the cam surface intersects the back side of the tooth at the leading edge of the tooth.

Abstract: An engine starter having an internal liner which carries forward the motor and gear reducing assembly in unison to engage the engine simultaneously providing a limited power rotation to the pinion and subsequently full power to the engine starter once engaged at movement of the liner performs the valving function to permit the so-called "soft" starter engagement.

Abstract: A rotatable flange device for mounting a starter to an engine thereby permitting ready orientation of the starter and associated connections to adapt the starter configuration to a wide variety of engines, mounting positions, and vehicles.

Abstract: This invention relates to a liquid-cooled piston ring carrier assembly and piston for internal combustion engines. The ring carrier assembly includes an annular metallic body and an enclosure member collectively defining an integral coolant channel. During engine operation, liquid coolant is directed to the coolant channel by way of an inlet passage in the skirt portion of the piston and an aligned inlet port in the ring carrier assembly. An outlet passage in the skirt portion of the piston and an aligned outlet port conveys coolant away from the coolant channel.
