摘要： A pump has a boltless cover that is held on the end of a housing of the pump by only a compressed ring between the cover and the housing. The pump has a flageless valve plate, meaning that the valve plate has no flange through which bolts that secure the head to the pump extend The pump has eccentrics and pistons that all have holes in them so that the pistons at opposite ends of the pump can be assembled to the shaft of the motor 180° out of phases. The pump further has a monolithic head that includes the two head members of the pump and the tube that connects them also has an integrally formed port. The pump is supported by elastomeric tubular members from its ports. The pump has a push-in fitting that can be pushed into a hole in a member such as the heads the housing or the base so that once pushed in, a ring around the fitting expands outwardly behind an edge of the body to trap the fitting in the opening.

摘要： A two-cylinder air compressor has a motor with a through drive shaft. Identical housings are provided at each end of a cylindrical spacer sleeve that surrounds the motor. The housings include cylinder housing extensions each of which mounts a cylinder sleeve, a valve plate, and a head. The heads are part of a one-piece cylinder head member. Wobble pistons are mounted on each end of the motor shaft and operate in the cylinder sleeves. The cylinder sleeves rest on a floor in the housing which has integrally formed passages for cooling air to circulate around the cylinder sleeves. The one-piece cylinder head member includes integral tubes connecting the heads. The integral tubes span the distance between the beads and are spaced from the outside of the spacer. The housings may be joined by through bolts or without bolts by press fitting the bearings in the housing, press fitting the housings to the spacer sleeve, and press fitting the motor shaft into the bearings. The one-piece cylinder head serves as the final retention member, clamping the housings axially while maintaining radial orientation.

摘要： A compact 180° opposed piston pump/compressor minimizes axial spacing between its pistons on the drive shaft and has mass-balanced pistons designed to reduce the shaking couple and noise from reciprocation of the pistons. The piston assemblies can have members, such as cup retainers, that are of different masses selected to compensate for the difference in piston masses and thereby equalize the masses of the pistons. Each piston assembly can be mounted to the drive shaft at eccentrics that occupy minimal or no space between the pistons.
摘要翻译：紧凑的180°相对的活塞泵/压缩机使驱动轴上的活塞之间的轴向间距最小化，并具有大量平衡的活塞，旨在减少振动对和噪音从活塞往复运动。活塞组件可以具有不同质量的构件，例如杯保持器，用于补偿活塞质量的差异，从而均衡活塞的质量。每个活塞组件可以以偏心运动的方式安装在驱动轴上，这些活塞在活塞之间占据极小的空间或没有空间。

摘要： A pump uses tubular transfer members for transferring intake and/or exhaust air into the crankcase and/or between valve head chambers. The pump has compact 180° opposed pistons that minimize axial spacing between the pistons on the drive shaft and thereby reduces the shaking couple and noise from reciprocation. Each piston has its own eccentric element press-fit into the connecting rods so as not to occupy space between the pistons. The shaking couple can be further reduced for pistons of different masses by selecting the mass of the cup retainers to compensate for the difference in overall piston masses. The pump includes an improved cylinder sealing arrangement having a circumferential groove in an angled surface at the end of the cylinder. The pump also has a special cover and seal for closing the open neck of the pump crankcase and a multi-lobed valve stop.

摘要： A pump has a flapper valve structure with recesses around a valve mounting area that receive locator pins during assembly to locate and retain the flapper valve during assembly, and an armed valve stop. The pump uses tubular transfer members for transferring intake and/or exhaust air into the crankcase and/or between valve head chambers. The pump has compact 180° opposed pistons that minimize axial spacing between the pistons on the drive shaft and thereby reduces the shaking couple and noise from reciprocation. Each piston has its own eccentric element press-fit into the connecting rods so as not to occupy space between the pistons. The shaking couple can be further reduced for pistons of different masses by selecting the mass of the cup retainers to compensate for the difference in overall piston masses. The pump includes an improved cylinder sealing, arrangement having a circumferential groove in an angled surface at the end of the cylinder. The pump also has a special cover and seal for closing the open neck of the pump crankcase and a multi-lobed valve stop.
