摘要： In order to decrease internal friction of a heat engine that converts a reciprocating motion of a piston into a rotational motion, a piston apparatus (1) forms an air bearing between a crankshaft (30) and a bearing unit (9B) provided in a crankcase (9) and between an eccentric portion (30c) of the crankshaft (30) and a large end portion (201) of a connecting rod (20) by feeding a gas therebetween from a crank-side hollow portion (31) of the crankshaft (30). The piston apparatus 1 also forms an air bearing between a piston pin (40) and a small end portion (202) of the connecting rod (20) by feeding a gas therebetween from a piston pin-side hollow portion (43) in the piston pin (40).

摘要： An air balance structure that compensates for the weight load of a movable member driven in a straight line along the vertical axis, with a simplified structure and at reduced cost. The box-shaped movable member has an open bottom that accommodates the stationary member therewithin, in which state the movable member is movably supported in the vertical direction by an air bearing created using a gap between the stationary member and the movable member. An air balance chamber that contains pressurized air is formed inside the movable member. After pressure-adjusted air is supplied from the outside to the gap from a jet port through a pipe inside the stationary member, the air flows into the air balance chamber. This flow seals the pressurized air inside the air balance chamber. Pressurized air exhaust is exhausted externally from an exhaust port through a pipe and a flow adjusting device.

摘要： A variable capacity hydraulic machine has a rotating group located within a casing and a control housing secured to the casing to extend across and seal an opening in the casing. The control housing accommodates a control circuit and a pair of sensors to sense change in parameters associated with the rotating group. One of the sensors is positioned adjacent the barrel on the rotating group to sense rotational speed and the other senses displacement of the swashplate. The control housing accommodates a control valve and accumulator to supply fluid to the control valve.

摘要： A machine tool comprising a base, with a guide surface, a workpiece holder on the base, a movable tool carriage, and a motor for advancing the carriage along the guide surface toward the workpiece. Hydrostatic bearings are situated in the carriage for discharging fluid, such as oil, into the narrow gap defined between the carriage and the guide surface. A pre-load rail is secured to the movable carriage, and a plurality of pockets are defined in the pre-load rail. A hydrostatic pre-load piston, with an enlarged head and a depending base, is located in each pocket. A shallow depression is formed in the face of each piston, and an annular wall surrounds the depression, so that the piston restores itself to an equilibrium condition. The pre-load pistons are located in opposition to the hydrostatic bearings. An O-ring encircles the base of the piston, and allows floating, and tilting, movement of the piston within the pocket, while serving as a seal for the pocket. The individual pre-load pistons float and tilt to accommodate diverse localized distortions, anomalies, imperfections, machining errors, and the like, in the carriage, and in the guide surface.
