Abstract: An air compressor utilizing one or more pistons reciprocating within water cooled cylinders and operating in an oil free environment. Each piston is reciprocated by rotation of motor driven, balanced rotors, through a reciprocating and oscillating shuttle member. A centrally sleeved, hollow ball, accommodates shuttle member movement, while interconnecting the shuttle member and the rotors. Positive lubrication is provided for the rotor bearings, the hollow ball and shuttle member and the reciprocating piston shafts. The rotors are driven in opposite directions by motors mounted to maintain constant torque on the rotors.

Abstract: A double acting piston pump for cryogenic mediums is disclosed. The pump includes a vertically positioned cylinder having a base portion and a cover portion, and inlet valves are disposed in the cover portion and the base portion for admitting the cryogenic medium into the cylinder and for providing a pressure component of approximately zero against the direction of flow of the cryogenic medium. Outlet valves are disposed in the cover portion and the base portion for discharging the cryogenic medium from the cylinder. A piston is slideably mounted in the cylinder and a drive rod connected to the piston extends through either the cover portion or the base portion of the cylinder. A drive arrangement engages the drive rod for actuating the piston. A housing is also provided which has a portion defining the cylinder. The drive rod and the drive arrangement are mounted in the remaining portion of the housing, whereby the housing is common to the piston, the drive rod and the drive arrangement. The pump is suitable for both liquid and gaseous mediums and generates practically no frictional forces.

Abstract: The disclosure concerns cylinder barrels for piston pumps and motors which have lined cylinder bores. Each liner comprises a matrix of sintered, powdered iron which is impregnated with bronze, and which is metallurgically and mechanically bonded to the steel barrel. The liners are formed from porous, sintered iron sleeves which are placed in the bores in contact with bronze slugs. The assembly is heated in a non-oxidizing atmosphere to a temperature between 1,900*F and 2,000*F to melt the bronze and cause it to infiltrate the sintered preform and bond to the steel. Thereafter, the assembly is cooled in the non-oxidizing atmosphere to solidify the bronze, followed by air cooling to room temperature. Finally, the finished cylinder bores are machined in the bonded bronze-iron sleeves.

Abstract: There is provided a high pressure fuel pump which includes a reliable fuel seal having a long durability and which can be produced at a relatively low cost. When a rotating shaft 4 is rotated to rotate a swash plate 7, such rotation is transmitted to a piston shoe guide plate 8 through a thrust ball bearing 9. Since the plate 8 is supported by a spherical portion 16 of a rod 14 mounted to a body 12, the plate 8 performs a precession to recurrently operate a plurality of fuel pumps 21 to 25 disposed around the rod 14. Each of the fuel pumps 21 to 25 includes a bellows provided between an outer end of the piston and the body 12, and the bellows completely seals a fuel leaked from a sliding clearance between the piston and the cylinder. Since the leaked fuel is introduced into a return passage 19 through a groove formed in an outer wall of the cylinder, a large internal pressure is not applied to the bellows and therefore, the bellows can be made of a low-priced material such as Teflon.

Abstract: A pump configured so that tools are not required to remove the pump head and disassemble the plunger. A single large hand operated knob or head nut facilitates tool-less pump head removal. The pump head is guided into position in a manifold and held in place by the hand knob. The manifold is designed to receive all the external fluidic connections made to the pump head. Fluid paths to the pump head have been replaced with miniature face seals which facilitate high pressure sealing between the pump head and manifold. Low pressure tubing seals reside in a seal wash chamber or housing and are not attached to the head, eliminating the need for tooling to disconnect them during pump head removal. A tool-less plunger mechanism includes a nutcap assembly having a plunger socket receiving a plunger assembly including a sapphire plunger fixed to a plunger holder ball accommodated by the socket. The plunger assembly is captured within the socket by a plurality of cams. The cams are spring loaded to rotate and collapse onto the plunger holder ball, pulling the plunger assembly tightly into the socket. A restricting cone is actuated to rotate the cams away from the plunger holder ball for release and removal of the plunger assembly.

Abstract: Piston assemblies for use in fluid translating devices normally are made of hardened metal alloy materials which require very smooth surface and are always subject to varying degrees of thermal expansion when being operated at high operating temperatures. In the subject arrangement, a piston assembly is provided and is constructed of most, if not all, ceramic components. The piston assembly includes a ceramic piston having a spherical head portion at one end thereof which rests in a spherical cavity of a ceramic slipper and held therein by a cylindrical ring. The cylindrical ring can be of a one-piece or a two-piece design which is in contact with the spherical head portion and bonded to the ceramic slipper, thus, retaining the spherical head portion. The cylindrical ring could also be made of a metallic material. The metallic ring is bonded to the ceramic slipper and subsequently swaged to hold the spherical head portion within the spherical cavity. The subject ceramic piston assembly provides a very smooth surface which reduces sliding friction and likewise the effects of thermal expansion and inertia are minimized by the use of a ceramic material. Consequently, the subject piston assembly is very efficient when operating at high temperatures and, likewise, is easy to manufacture and assemble.

Abstract: Arcuate bearings are useful, for example, in pivotally supporting a cradle swashplate of axial piston variable displacement hydraulic devices. The bearings of known hydraulic devices have either been a pair of laterally spaced roller bearings assembly or a pair of laterally spaced sleeve bearings. The subject hydraulic device includes a roller bearing assembly positioned between the swashplate and the housing at the side of the swashplate subjected to high loads and a less expensive sleeve bearing positioned between the swashplate and the housing at the other side of the swashplate subjected to low loads. By using this combination of bearings, the overall cost of the hydraulic device is reduced without impairing the operation of the hydraulic device.

Abstract: The piston mechanism comprises a piston (3), a sliding shoe (6) and a coupling member (18) holding together the piston (3) and sliding shoe (6). The coupling member (18) comprises a shaft part (19) and joint heads (20,21) arranged at the end of the shaft part (19). The heads (20,21) have spherical zone-shaped sliding surfaces (9,11,23,24), which cooperate with corresponding sliding surfaces (9,24) in sliding shoe (6) or in the bottom of the piston (3). Due to the fact that the radius of curvature (R1,R2,R3) of the sliding surfaces of the sliding shoe (6) and the piston (3) have the same centre of curvature (10) and therefore the same fulcrum, damage to the sliding surfaces is avoided.
