摘要： This invention relates to a fluid operated hydraulic pump which includes a housing (10), a chamber (22) in the housing with at least a portion of the wall (12) of the chamber being movable towards and away from a second wall to vary the volume of the chamber, a fluid inlet port (55) into and an outlet port (56) from the chamber (22), a valve arrangement (16) for opening and closing the fluid inlet (55) and outlet ports (56), a hydraulic fluid piston pump (14) which is attached to the housing (10) with its piston (32) connected to the movable chamber wall (12) and means which is actuated by the hydraulic pump piston (32) for operating the valve arrangement (16) to close the housing chamber (22) fluid outlet port (56) and to open its inlet port (55) to enable fluid under pressure to enter the chamber (22) to move the movable chamber wall (12) away from the second wall to cause the hydraulic pump piston (32) to pump hydraulic fluid at an amplified pressure from the hydraulic pump (14), in use. Preferably the valve arrangement (16) is situated in the housing chamber (22) and the movable wall portion (12) of the chamber is defined by a flexible diaphragm assembly.

摘要： An air-operated pump for pumping material such as oil or grease. The pump is powered by an air motor which operates to reciprocate a piston and plunger to effect a pumping action. The air motor is modular in that the air valve system is contained in a single housing fastened to the pump head. The housing is removable as a unit from the pump head to facilitate servicing of the air valve system.

摘要： An air motor comprising a piston and cylinder unit and control means mounted wholly within a housing secured to the unit. The housing comprises two parts (11, 12) at the ends of the cylinder (10) and a manifold assembly (28, 30) extending alongside the cylinder (10) and these end parts. The control means comprises a changeover valve (25) in the manifold assembly and two control valves (26, 27) in the respective end parts (11, 12) which are operated by mechanical actuators (K 1, K2) engaged by the piston (13) when it reaches the ends of its stroke and thereupon cause the changeover valve to change over the supply of compressed air from an inlet (60) in the manifold assembly, from one end of the cylinder to the other thereby to reverse the movement of the piston so that the piston reciprocates in the cylinder. The piston may comprise two parts (51, 52) which are adjustable to vary its effective length and hence its strocke.

摘要： The object of the invention is to provide a device for digital hydraulic pressure transformation with low loss, intended for flow- and power control for hydraulic machines, particularly hydraulic cylinders, which via a switching device are connected to a pressure reservoir with constant high pressure. According to the invention an intermediate mass is present between the switching device and the hydraulic machine which mass is activated by the flowing medium, the intermediate mass being of such size that the average velocity of the flow in the pipe during the open period of the switching device is sufficiently low to bring the hydraulic medium into the hydraulic machine so slowly, that the pressure change at the location of the hydraulic machine is smaller than the pressure difference between the reservoir and the momentary pressure at the location of the hydraulic machine, as result of which a gradual stepwise rising or lowering of said pressure level is made possible.

摘要： Este motor de tres tiempos utiliza el movimiento oscilatorio de un pistón doble (2) producido por las explosiones de combustible en cámaras de combustión (6), para mover un bombeador (7) que succiona aceite desde un estanque (15) y envía pulsos hacia un acumulador (16) y una válvula reguladora de flujo (17), transforma los pulsos en flujo continuo que mueve un motor hidráulico (18. El motor es de tres tiempos, porque tiene tiempos de compresión, expansión y detención, durante la detención se realiza el ciclo de abertura y cierre de las válvulas de escape (10) y admisión (9). El pistón doble se detiene por equilibrio de fuerzas entre la presión de los gases combustionados y la suma de las fuerzas de la presión de compresión y la presión hidráulica sobre el bombeador, la válvula de bloqueo (14) detiene el pistón doble hasta el momento de producirse la ignición.

摘要： Apparatus for pumping a stimulant fluid in a hydraulic fracturing system comprises an engine and a pressure converter arranged in use to be driven by the engine at a first pressure, and to pump stimulant fluid at a second, higher pressure. A pair of primary hydraulic loading actuators (210) translate load via a loading beam (212) into two pairs of displacement actuators (214). The primary hydraulic loading actuators (210) are arranged in diametric opposition and are arranged to move in the direction of arrows A in a reciprocating manner. The displacement actuators are used to displace stimulation fluid in a wellbore (not shown) for the fracturing of subterranean strata. Two sets of displacement actuators are used, again in diametric opposition in an alternating cycle, and moving in a reciprocating manner in the directions of arrows A.
