Two yokes are pivotally mounted on the frame, each having complimentary surfaces to the other yoke and to the frame, minimizing the space occupied by the yokes. Stop means ... | 02/14/2006 |
| 6988441 | Rotary engine An engine includes a rotatable member with one or more cylinders disposed tangentially around its circumference. There are one or more corresponding pistons, each piston is associated with a piston lever pivoted eccentric to the rotatable member. Movement of each pi... | 01/24/2006 |
| 6705202 | Rotary engine An engine includes a rotatable member with one or more cylinders disposed tangentially around its circumference. There are one or more corresponding pistons, each piston is associated with a piston lever pivoted eccentric to the rotatable member. Movement of each pi... | 03/16/2004 |
| 6492033 | Lead-free plain bearing and method for its manufacture A lead-free plain bearing is formed by dispersing an alloy powder formed from 7-13 mass percent of Sn, 0.1-5 mass percent of Ag, and Cu on a backing, such as a steel plate, and sintering. The alloy powder may further include one or more of 0.05-0.5 mass p... | 12/10/2002 |
| 5205124 | Piston motor with starting charge device A hydraulic piston type motor having a rotating piston barrel abutting a fixed porting plate or head with a starting charge device including a differential area piston operating to supply a limited hydrostatic pressure between the porting plate and rotati... | 04/27/1993 |
| 5182977 | Hydraulic centrifugal piston motor An hydraulic centrifugal piston motor having mulitple piston circumferentially disposed at right angle to shaft axis, having a rotational power moment that occurs twice each revolution for each cylinder. The power stroke for each cylinder would occur for ... | 02/02/1993 |
| 4748895 | Multiple stroke radial piston motor with radially extending guide segments on the rotor and with four rollers carried by each stroke transfer body The former art provides multi-stroke hydrostatic motors, which perform at a single revolution of the rotor multiple inward and outward strokes of the pistons. A high torque was thereby obtained. The invention discovers, that the know multi-stroke motors h... | 06/07/1988 |
| 4058088 | Oscillating piston engine An oscillating piston engine capable of running on a working fluid such as steam or compressed air comprises a bank of cylinders mounted for rotation in unison to turn a shaft in an engine block, pistons mounted for oscillation in the cylinders and rotata... | 11/15/1977 |
| 3974801 | Oscillating piston internal combustion engine An oscillating piston internal combustion engine comprises a bank of combustion chambers mounted on the front of an engine block for rotation in an annular path to rotate an output shaft protruding from the rear of the block. Gearing inside the block conv... | 08/17/1976 |
| 3968776 | Rotary crankless machine A rotary crankless machine in which there is a rotary shaft, a rotary cylinder block, and a stationary housing, all concentrically disposed about a common axis and in which the housing has a central annular manifold block with inlet and outlet passages di... | 07/13/1976 |
