摘要： An internal combustion barrel engine includes an engine housing with a first and second end. An elongated power shaft is longitudinally disposed in the engine housing and defines a longitudinal axis. A combustion cylinder and a guide cylinder are spaced apart and disposed on a common cylinder axis that is generally parallel to the central axis. The cylinders each have an inner end and an outer end, with the inner ends being closer to each other. The outer end of the combustion cylinder is closed. An intake system is operable to introduce a mixture of air and/or fuel into the combustion cylinder. A track is supported between the inner ends of the cylinders and has an undulating cam surface. The track is moveable such that the portion of the cam surface most directly between the cylinders undulates toward and away from the inner end of the combustion cylinder. A double-ended piston includes a combustion end disposed in the combustion cylinder so as to define a combustion chamber between the combustion end and the closed end of the combustion cylinder. A guide end is disposed in the guide cylinder. A midportion extends between the combustion end and the guide end and is in mechanical communication with the guide surface of the track. A variable compression ratio device is operable to move the track axially towards and away from the inner end of the combustion cylinder so as to adjust the compression ratio. Combustion occurs only in the combustion cylinder and does not occur in the guide cylinder.

摘要： A closed cavity piston assembly includes a piston body, a separately formed piston cap sealingly joined to the body, and an elongated stem integrally formed with one of the piston body or the cap. In one embodiment, the stem is integrally formed with the piston body. In another embodiment, the stem is integrally formed with the piston cap and slidably journaled in and sealed to a hole in the bottom of the piston body. The cap of the piston assembly also has a surface for engaging a slipper. In either case, a fluid passageway extends through the stem, body, and cap of the piston assembly. The passageway is remote from the side wall of the piston body and fluidly isolated from the main interior cavity of the hollow piston body once the cap and body are sealingly joined together. The piston assembly can be pivotally attached to a slipper that has its own fluid passageway, which registers with the passageway in the cap, to provide fluid for slipper lubrication and balance.

摘要： In a master cylinder, a sleeve for guiding the piston and a cap for forming a cylinder housing are connected with each other and integrally formed, and a primary piston and a secondary piston are coupled with via a retainer and thus integrally formed. Consequently, when the master cylinder is disassembled, the sleeve and the piston can be pulled out simultaneously, thereby allowing the simultaneous withdrawal of the secondary and primary pistons.

摘要： A ball and socket joint for use in mechanical linkages, especially for ball-ended connecting rods in a multi-cylinder hydraulic pump comprises a ball head forcibly inserted into a socket which extends over more than a hemisphere and which is formed as a cylindrical seating member. Radial slits around the mouth of the socket allow the necessary distortion and then the mouth of the socket is squeezed and held by a hoop or ring or counter-plates, and the seating member is inserted in a cylindrical recess in a further component.

摘要： A piston for a hydrostatic machine comprises a cam follower ball in a seating in a piston body. An aperture through the piston body provides access for working fluid to reach the seating to give lubrication and hydrostatic support. A low friction insert of synthetic plastics material in the seating provides a bearing surface for the ball. The insert is retained in the piston body by a lip which prevents or inhibits extrusion of the plastics material under working load pressure.

摘要： A POSITIVE DISPLACEMENT FLUID DEVICE HAVING A BIASING SPRING ASSOCIATED WITH THE PISTONS FOR URGING THE PISTONS OF THE FLUID DEVICE TOWARD A CAMMING SURFACE WHICH INDUCES PISTON RECIPROCATION. THE BIASING SPRINGS ARE OF A PREDETERMINED LENGTH LESS THAN THE LENGTH OF THE PISTON STROKE SO AS TO ENGAGE AND ACT ON THE PISTON ONLY DURING A PREDETERMINED PORTION OF THE PISTON STROKE THEREBY REDUCING SPRING FLEXURE AND FATIGUE, YET PROVIDING SUFFICIENT BIASING FORCE TO CONTINUOUSLY OVERCOME THE TENDENCY OF THE PISTON TO LIFT OFF THE CAM. IN THE PREFERRED EMBODIMENT, THE LENGTH OF THE SPRINGS APPROXIMATE THE MEAN

DISTANCE OF THE PISTON STROKE AND BIAS THE PISTON ONLY THROUGH THAT HALF OF THE STROKE DURING WHICH THE PISTON ACCELERATES TOWARD THE CAM SURFACE. IN OTHER ARRANGEMENTS, THE LENGTH OF THE SPRING MAY BE VARIED TO ACT FOR MORE OR LESS THAN ONE-HALF OF THE STROKE AND, EITHER SINGLY OR IN CONJUNCTION WITH OTHER BIASING MEANS, PROVIDE INITIAL PRELOAD ON THE PISTON AT THE ZERO DISPLACEMENT POSITION OF VARIABLE DISPLACEMENT UNITS.

摘要： A variable-delivery axial piston pump wherein the heads of pistons are biased toward the wobble plate by a star-shaped plate spring which is free to swivel on the drive shaft. Followers which engage balls provided in the wobble plate abut with their flat rear faces against flat end faces provided on the heads of pistons so that the followers can move radially with reference to the pistons when the inclination of the wobble plate is changed to change the delivery of the pump.

摘要： A SINGLE ACTING STEAM ENGINE WHEREIN MEANS ARE PROVIDED FOR AUXILIARY EXHAUST THROUGH THE PISTON WHEN THE AUXILIARY EXHAUST POPPET IS OPEN AND THE AUXILIARY EXCHANGE PASSAGES OF THE PISTON REGISTER WITH THE EXHAUST PORTS IN THE CYLINDER WALL. THE OPENING AND CLOSING OF THE AUXILIARY EXHAUST POPPET ARE RESPONSIVE TO THE RATE OF RECIPROCATION OF THE PISTONS. A MULTIPLE OF SAID ENGINES MAY BE UTILIZED ON COMBINATION TO PROVIDE A MULTIPLE CYLINDER POWER PLANT. THE ENGINES MAY BE ADAPTED TO DRIVE A SWASH PLATE DRIVE.
