Abstract: In an epitrochoidal rotary air compressor, a stationary portion includes a stationary single offset power shaft on which is mounted an epitrochoidal rotor in a rotary housing portion. The rotor includes a pinion gear which cooperates with a ring gear in the rotary housing portion to move the rotor within the rotor chamber in the rotary housing portion. A centrifugally driven lubrication system including lubrication channels extending internally of the stationary power shaft is provided for lubricated bearings and gears within the apparatus. An improved compression seal engaging the lateral faces of the rotor has a plurality of buttons biasing a split ring against the lateral faces of the rotor. An air pressure unloader valve is centrifugally operated to release the load from the compressor during startup. A rotary after-cooler in the rotary housing portion removes thermal energy from the compressed air prior to leaving the compressor and an inter-cooler may be provided in a two stage compressor.

Abstract: A rotary distributor fuel injection pump includes a rotary distributor member movable axially in a body part. The distributor member has a transverse bore in which is mounted a pumping plunger. At its outer end the plunger is engaged by a cam follower including a roller which is axially movable with the distributor member and which engages cam lobes formed on the internal surface of a cam ring to effect inward movement to the plunger. Outward movement of the plunger is effected by supplying fuel to the bore and the extent of outward movement of the plunger is limited by stop rings on the opposite sides of the cam ring. The stop rings are mounted in the body and define internal inclined surfaces which are engaged by end portions of the roller so that as the distributor member is moved axially the extent of outward movement of the plunger will be varied to control the amount of fuel supplied by the pump.
