    Abstract: A piston (8) is provided in a motor main body (4). A first motor chamber (9) is provided above the piston (8) and a second motor chamber (10) is provided below the piston (8). A pilot valve element (18) is provided so as to protrude from the piston (8). When a supply/discharge valve (13) is moved to its upper limit position or its lower limit position by the movement of the pilot valve element (18) in an up-down direction, a first valve member (25) of the supply/discharge valve (13) switches between supplying and discharging pressure fluid to and from the first motor chamber (9) and a second valve member (26) of the supply/discharge valve (13) switches between supplying and discharging pressure fluid to and from the second motor chamber (10).

    Abstract: A high pressure double membrane pump has a central housing (3), two cylindrical pump chambers (7,8), a coupling rod (4) which moves back and forth when the pump is in operation and which has a pump piston (9), two membranes which divide each of the pump chambers (7,8) into a product chamber (11,12) and a compressed air chamber (1,2) with changing volumes of which the membranes have a peripherally mounted membrane body (15). In the central area of the membrane body (15) a rigid implant body (17) is embedded which is equipped with a dog (18) which is connected to one end of the coupling rod (4), and a pneumatic control unit for the alternating impinging of compressed air upon the compressed air chambers. In the area of the compressed air chambers (1,2) a rigid supporting ring (20) is pushed onto the dog (18) between the end of the coupling rod (4) and the inner side of the membrane (5). The diameter of said supporting ring is between 50% and 95% of the diameter of the working surface of the membrane (5), and the periphery thereof is formed as a rounded shoulder (21) facing away from the membrane body (15).

    Abstract: A compressor system that is configured to compress the fluid from low pressure source to a higher pressure magnitude is powered from the same low pressure fluid source. The compressor system includes two piston assemblies that are coaxially coupled to one another, and that are of differing cross sectional areas. The low pressure fluid is used to move the larger piston assembly, which is in turn used to move the smaller piston assembly. Low pressure fluid is selectively admitted to the smaller piston assembly, and movement thereof is used to compress the low pressure fluid to a higher pressure magnitude. The compressor system uses a fluidic bistable amplifier, which also coupled to the low pressure fluid source, to control low pressure fluid flow to the larger piston assembly, to thereby control its movement.
