Abstract: The present application is directed to a system for converting linear motion to rotary motion. The system includes at least first and second cylinders. The first and second cylinders are in fluid communication with each other. The system also includes a first piston. The first piston is slidably disposed in the first cylinder. The system further includes a second piston. The second piston is slidably disposed in the second cylinder. The first and second cylinders contain an incompressible fluid. The first piston is in operative connection with the second piston such that movement of the first piston in a first direction causes movement of the second piston in a second direction, wherein the second direction is opposite the first direction.

Abstract: Today, the world is faced with many problems such as the Greenhouse Effect, global warming, ozone layer depletion and increased pollution. One direct cause of these problems has been linked to the emission from internal combustion engines. One way to combat these problems is to create a system which utilizes a small internal combustion engine or electrical motor coupled with a hydraulic network. The hydraulic network will exponentially increase output energy without raising the emission levels. In the case where an electrical motor is being used, there is a complete void of pollutants. This motor/hydraulic coupling not only helps save the environment, but provides a cost-effective means of power.

Abstract: The present invention comprises an input drive system, which provides a plurality of phases of oscillating fluid flow, and an output drive system connected directly to the input drive system that is powered by the plurality of phases of oscillating fluid flow. The input drive system comprises a plurality of pistons that are caused to move in a reciprocating fashion by a power source. The power source may be a rotating power source, such as that provided by an electric motor, a diesel or petrol engine, or a turbine system. The input drive system comprises a cam ring attached to a rotating power source; a plurality of cam rollers in contact with the cam ring; and a plurality of pistons attached to the cam rings. The output drive system comprises one or more pistons that are caused to move in a reciprocating fashion by the oscillating fluid flow provided by the input drive system.

Abstract: A utility vehicle or other utility device includes a hydraulic circuit that enhances operative capabilities of utility mechanisms with multiple hydraulic functionality. In some embodiments, multiple functionality can include powering of one or more hydraulic motor(s) and/or one or more hydraulic cylinder(s).

Abstract: A drive mechanism for driving a shaft in unison with a wheel. The drive mechanism includes a plurality of slave pistons and a like plurality of master pistons. Each slave piston is paired with a master piston to establish a plurality of paired pistons. A cam is operatively coupled to the wheel and to the master pistons to cause the master pistons to move between retracted and extended positions when the wheel is rotated.

Abstract: The device comprises a manipulator (148) whose body (149) houses deformable positioning transmitter bags (145 to 147) each connected by a corresponding hydraulic circuit to a positioning receiver comprising a deformable bag (130 to 132, 133 to 135), whose increases in volume in response to the compression exerted by the user on at least one of the positioning transmitter bags (145 to 147 control a change of the positioning of at least one controlled member. The device may contain a connector connecting the transmitter bags to the receiver bags, and also path switching hydraulic circuits permitting the selective control of one of two different members by a single manipulator. Application in particular to the control of external rear view mirrors on vehicles.

Abstract: The apparatus has at least one cam plate driven by a drive shaft in a piston pump or hydraulic pressure generator. The cam plate has a cam track or surface with at least two substantially sinusoidal protrusions and recesses or depressions on its circumference or perimeter. The rotation of this cam plate drives a crankshaft of a hydraulic piston and cylinder drive unit or motor by means of at least one plunger or cam follower or tappet and a piston through at least one transmission pipeline or conduit filled with a hydraulic medium. This transmission pipeline is attached without valves to the cylinder of the piston and is connected by means of an also valveless cylinder with a piston of the hydraulic piston and cylinder drive unit or motor.

Abstract: This hydraulic coupling mechanism consists of at least a pair of pressure transmitting cylinders which are operated in a predetermined sequence, at least a pair of pressure receiving cylinders synchronously operated by the pressure transmitting cylinders through corresponding closed liquid lines, each of which is provided with a corresponding pressure adjustable cylinder.
