Abstract: A peristaltic down-hole drilling motor comprises a series of breathing working chambers that are formed between a membrane and a tubular section of the stator of the motor.The rotor comprises a plurality of rollers that are rotatably supported in grooves of a carrier body such that the rollers press the membrane at selected intervals against said tubular section.The working chambers are designed such that during operation of the motor the rollers are actuated to ride upon the membrane in front of the expanding portions of the chambers, thereby rotating the rotor relative to the stator.

Abstract: There is disclosed an operator in which flexible bags are disposed between adjacent vanes and fixed walls on a rotatable shaft and a housing, respectively, which extend across an annular chamber formed by the shaft and housing and arranged concentrically about the shaft. Pressure fluid is selectively admitted to bags on one side of the vanes while being exhausted from bags on the other sides of the vanes so as to cause the vanes to rotate between alternate positions within the chamber.

Abstract: A new and improved electrochemical actuator and method of using it enables a reversible electrochemical generation of gases for inducing a phase/volume change that can produce high actuation forces, long actuation distances, and remain at the last pressure level attained by current flow even after the power is switched off, enabling a zero power hold at any position. The electrochemical actuator includes an electrolyte solution sealed within a substantially constant volume chamber, having electrical contacts disposed therein such that the electrolyte is in electrical communication with the electrical contacts. Passage of current between the contacts through the electrolyte, separates the electrolyte and or electrode material into its component gas or gases, resulting in an increased pressure within the chamber. This pressure can either act directly upon, or be routed via pneumatic or hydraulic lines, to actuate a diaphragm, move a piston, inflate a bladder, or any other suitable means of converting pressure to motion or displacement. The electrochemical actuator of the present invention can be scaled-up for large scale applications, or down-scaled for micro-miniaturization applications. Because of its low voltage and current requirements, the present electrochemical actuator is fully compatible with modern semiconductor circuits. Furthermore, the electrochemical actuator of the present invention can be operated over a wide temperature range and inexpensively manufactured in large quantities.

Abstract: A hose piston is disposed inside a flexible hose which is filled with fluid and movable in any direction upon hydraulic pressure. The rollers of an external device are engaged on the exterior surface of the flexible hose and are located adjacent to the midsection of the hose piston. The fluid pressure inside the flexible hose forces the hose piston to move along a given direction within the flexible hose, which in turn forces the rollers to travel in the same direction. This mechanism can transport the external device along the flexible hose.

Abstract: The invention relates to a prime mover of the radial type. The mover is driven by rod-like driving elements which are eccentrically linked to the shaft and are essentially radially directed. The other end of each of the driving elements is connected to a diaphragm of the bellows type which encloses a pressure chamber. The pressure chamber alternately is loaded and exhausted with pressure medium depending on the rotating movement of the shaft thus acting on the driving elements whose oscillating movements are directed to the shaft and transformed to a rotary movement.
