Abstract: An improved axial-piston energy converting device is provided by utilizing a thin ceramic wear plate insert, having a typical thickness of only about 0.005 to 0.040 inches in thickness, as a cam surface secured by atmospheric pressure to an underlying support surface of a steel cam plate support structure. Attachment of the wear plate to the cam plate supporting surface is accomplished by polishing both a supporting surface of the cam plate, and a mating surface of the wear plate to a very smooth finish, and wiping a thin film of a fluid such as oil onto one of the polished surfaces prior to placing the wear plate onto the supporting surface. The highly polished, together with the light film of oil, result in a joint that is essentially air tight. Atmospheric pressure acting on the cam surface of the wear plate serves to hold the wear plate tightly in place on the support surface in the same manner that a pair of Johansson blocks are held together if their highly polished surfaces are mated.

Abstract: A cylinder and piston construction for a compressor or vacuum pump has a cylinder defined by co-axial cylinder and guideway sleeves. The guideway sleeve is larger in diameter than the cylinder sleeve and the cylinder sleeve extends axially into the guideway sleeve. A piston has a cylindrical base which is guided via skirt bearings in the guideway and a head which extends from the base into the compression chamber defined by the cylinder sleeve and has a piston ring which forms a sliding seal with the cylinder sleeve. An annular cavity is defined between the piston head and the piston base into which the cylinder sleeve extends so that the top skirt bearing is positioned closer to the top of the piston head and further away from the bottom skirt bearing so as to steadily guide the piston head in the cylinder sleeve, thereby reducing wear and increasing the life of the pump.

Abstract: A swash plate type automotive air conditioning compressor that minimizes part count while providing a more robust and improved operation. A large diameter, single slotted ball located in a matching socket in each piston overlies the outer edge of the swash plate. As the plate turns, the sides of the plate rub along the sides of the ball slot, and the ball twists within the socket, reciprocating the piston. The larger diameter surfaces of ball and socket are easier to machine accurately, and part count is reduced to a minimum. The larger contacting surface areas provide for better lubrication and lower pressure loading.

Abstract: A direct suction hermetic compressor assembly is disclosed including a hermetically sealed housing having enclosed therein a compressor mechanism discharging compressed gas refrigerant into the interior of the housing, thereby creating a high pressure housing. The compressor mechanism includes a crankcase defining a suction cavity into which low pressure suction gas is directly introduced. Bearings in the crankcase communicate between the housing interior and the suction cavity, and rotatably support a crankshaft. Annular seals received within grooves in the crankshaft bear against the bearings and are actuated and lubricated by oil fed from within the grooves to prevent high to low pressure gas leakage and to facilitate bearing lubrication. A scotch yoke mechanism operably couples a plurality of radially disposed pistons to a crankshaft eccentric portion within the suction cavity. Oil ducts open onto the loaded surface of the eccentric to limit oil leakage into the suction cavity.

Abstract: The invention is a new linkage for connecting the piston and the piston actuator in a high pressure pump. All of the compression forces transmitted from the piston actuator to the piston by this linkage will be axial forces parallel to the axis of the piston since the linkage will not transmit forces to the piston which are transverse to its axis. This linkage allows the use of hard brittle materials such as ceramic materials in the piston because any misalignment between the axises of the piston actuator and the piston will not result in bending forces being applied to the piston which would cause it to break.

Abstract translation: 本发明是用于在高压泵中连接活塞和活塞致动器的新连接件。 通过该连杆从活塞致动器传递到活塞的所有压缩力将是平行于活塞的轴线的轴向力，因为连杆不会将力传递到横向于其轴线的活塞。 该连接允许在活塞中使用诸如陶瓷材料的硬脆性材料，因为活塞致动器的轴线和活塞之间的任何未对准不会导致施加到活塞上的弯曲力，这将导致其破裂。
