摘要： A high efficiency variable cutoff uniflow steam engine with piston operated valves has an exhaust valve that is held open by a spring during the exhaust stroke but is closed at an end of the exhaust stroke by the piston compressing steam in a compartment associated to act on the exhaust valve. The piston continues to move in the same direction a short distance toward top dead center (TDC) compressing a small residual quantity of steam in the cylinder above the piston during the remaining fraction of the exhaust stroke with sufficient pressure to open the steam inlet valve by steam pressure without an impact caused by physical contact with the piston.

摘要： A reciprocating compressor is provided. Bearing holes of a fluid bearing of the compressor may be positioned correspond to a full reciprocating region of a piston, to reduce/eliminate frictional loss and/or abrasion between a cylinder and the piston. The bearing holes may be concentrated at certain regions of the cylinder to stably support the piston through a full reciprocating range. Compression coil springs may maintain concentric alignment of the cylinder and the piston. Gas through holes may be radially formed at the piston to lower a pressure of a bearing space and allow refrigerant to be smoothly introduced into the bearing space through a gas pocket. A casing of the compressor may include an outer shell and an inner shell to attenuate vibration generated due to friction generated by operation of the reciprocating compressor.

摘要： An engine body includes a crankcase with a crank chamber therein, a cylinder block attached to the crankcase, and a breather passage which selectively permits fluid communication between the crank chamber and an area outside of the crank chamber. The engine body includes a one-way valve between the crank chamber and the breather passage, which allows a one-way flow of gases from the crank chamber to the breather passage. The one-way valve is pressure-operated and is operatively attached to a side wall of the engine body proximate a cylinder sleeve. The one-way valve may be mounted in a mounting window in a side wall of the crankcase, and a timing chamber may function as the breather passage. In an illustrative embodiment, the one-way valve includes a base plate having a valve hole formed therein, and a flexible reed valve plate with one end affixed to the base plate.

摘要： A compressed fluid motor has a plurality of cylinders with a piston and a piston rod. A main bearing is concentric with a crankpin and coupled to a shaft. Compressed fluid on the piston pushes on the main bearing via its corresponding piston rod. Bearing guide plates hold the one or more piston rod in place on the main bearing. A timing and control mechanism controls flow of compressible fluid to press on the piston and turn the shaft to perform work.

A link member is installed parallel to the axial direction of the cylinder or installed so as to extend obliquely to a direction parallel to the axial direction of the cylinder, and a first end of the link member is pivotably connected to a movable-side structure. A connecting member is fixed to the rod, and a second end of the link member is pivotably connected to the connecting member.

摘要： A non-internal combustion reciprocating engine has an enhanced mechanical advantage lever system for efficiently converting linear motion from reciprocating pistons to rotary motion at a crankshaft. The engine comprises a chassis, at least two sets of binary cylinder systems mounted on the chassis, a crankshaft and a lever system. Each lever system has a piston lever, two thrust rods and a central drive lever. Each piston lever is pivotally attached to the chassis and pivotally attached to a piston rod extending from a piston cylinder. The two thrust rods are pivotally attached at one terminus to the piston lever and pivotally attached at a second terminus to the central drive lever. The two piston cylinders of each binary cylinder system work in concert to efficiently transfer power to the crankshaft.

摘要： A dual rocking piston pump is disclosed which includes a first piston with a first connecting rod eccentrically mounted to a rotor shaft and a second piston with a second connecting rod eccentrically mounted to the rotor shaft. The rotor shaft passes through a first bearing and a second bearing before being connected to a rotor body. The rotor body is disposed within a stator. The first and second bearings and stator are supported by a bracket. The bracket includes a hub which, in turn includes a first end connected to a wall at an opening in the wall. The hub also includes a second end. The first end of the hub supports the first bearing at the wall and the second end of the hub supports the second bearing. Both the first and second bearings are disposed to “in front” of the motor or in front of both the rotor and stator. Because support for the rotor is provided entirely in front of the motor, no rear bell housing is required and because a single bracket supports the bearings, rotor and stator, fewer parts are required thereby making the pump lighter and more compact.

摘要： A hydraulic actuator for an active of semi-active vehicle suspension system has a cylinder with a piston therein. A piston rod is attached to the piston and extends out of the cylinder. First and second chambers are formed on opposites sides of the piston enabling the piston to be driven in a manner that counteracts vibrations in the vehicle, A third chamber is provided in the cylinder for connection to a load leveling apparatus. A novel structure reduces the overall length of the hydraulic actuator. A displacement sensor is incorporated into the hydraulic actuator to provide an electrical signal that indicated how far the piston rod extends from the cylinder.
