Abstract: An electromagnetic clutch having a bearing supported pulley provided with a compact rotor, coil and coil housing arrangement having precisely controlled and maximized air gap areas with the compactness characterized by allowing the inner diameter of the pulley to approach the outer diameter of the coil and the precise controlling and maximizing of the air gap areas characterized by the formation of a close tolerance radial air gap at substantially the outer diameter of the bearing.

Abstract: A variable displacement axial piston machine is disclosed having a piston guide cylinder stationarily aligned with an axial working piston cylinder. A single-headed piston has a piston head at one end reciprocally mounted in the working cylinder and a piston guide at the opposite end reciprocally mounted and guided in the guide cylinder to maintain axial alignment (prevent tilting) of the piston head in its cylinder during piston reciprocation. A shaft is supported for rotation about an axis extending longitudinally of and radially spaced from the piston and its cylinders and a rotary swash plate with flat parallel sides is fixedly drivingly and pivotally interconnected with the shaft so that the swash plate rotates with the shaft while being pivotal about a pivot axis transverse to the shaft axis.

Abstract: A liquid accumulator for air conditioning systems and the like having a hollow porous desiccant container which is adapted to be sealingly connected in the bottom of the accumulator's casing prior to permanent assembly thereof and wherein the desiccant container accommodates the accumulator's normal tube assembly and remains serviceable through the bottom of the casing for the adding and emptying of desiccant.

Abstract: A vehicle air conditioning system compact suction accumulator-dehydrator adaptable for multiple applications to trap liquid refrigerant flowing from the evaporator. The accumulator comprises a hollow vertically disposed tubular casing, providing top and bottom imperforate wall portions. The casing has an inlet and an outlet located in a side of the casing adjacent its top portion in substantial axial alignment. A generally U-shaped tube is located in the casing chamber with one end having a generally right-angled portion projecting into the outlet in a manner to hangingly support the tube in the chamber. An inverted cup-shaped baffle is supported in spaced relation on the tube other end for positioning in front of the casing inlet to provide a passageway from the inlet through the chamber to the inside of the tube.

Abstract: In a vehicle air conditioning system, an accumulator-dehydrator including a cylindrical housing with an upstanding standpipe located on the principal axis incorporating an improved plastic baffle having a generally frusto-conical skirt portion and an integral securing portion depending from the baffle closed upper end. The securing portion is spider-like in cross section, providing three spaced upwardly tapered webs each of which supports a vertically extending arcuate rib portion providing a press fit with the standpipe. Each rib terminates in a stop shoulder portion operative to seat on the standpipe open end to define passageways allowing vaporous refrigerant to flow upwardly along the baffle inner wall into the standpipe open end.
