摘要： The invention relates to a reciprocating engine and a working fluid inlet system therefore. The engine includes at least one cylinder (30) with a reciprocating piston (32) therein and a variable volume expansion chamber capable of receiving a working fluid via an inlet valve (40). The inlet system includes a pilot valve (34) having an open condition and a closed condition. In the open condition, the secondary fluid passes therethrough to act on the inlet valve (40). The system also includes an actuating means (18) for controlling the condition of the pilot valve (34). The inlet valve (40) is adapted to open in response to the action of the secondary fluid. The engine may also include exhaust means, possibly by porting in the piston (32) and a cylinder wall. The working fluid may be used as the secondary fluid.

摘要： A pilot control valve for controlling a reciprocating pump having a valve member shiftable within a valve body between a first or "downstroke" position and a second or "upstroke" position. When the valve member is in its first position, the valve member allows communication of control fluid to the lower surface of a piston to move the piston from a first position to a second position. As the piston reaches its second position, a vent in a rod attached to the piston allows control fluid acting on the valve member to depressurize. As such control fluid is depressurized, pressurized control fluid acts on the valve member to move the valve member from its first position to its second position. In its second position, the valve member blocks communication of the control fluid to the lower surface of the piston and allows communication of the control fluid to the upper surface of the piston causing the piston to return to its first position. As the piston returns to its first position, the vent in the piston rod allows the pressurized control fluid acting on the upper surface of the piston to act on the valve member to move the valve member back to its first position. In its first position, the valve member blocks communication of the control fluid to the upper surface of the piston and allows communication of the control fluid to the lower surface of the piston and the process is repeated. In this manner, the pilot control valve of the present invention achieves a consistent pumping rate for a reciprocating device coupled to the pilot control valve.

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： The invention refers to the construction of an aggressive liquids dosage membrane pump as entirety especially to the parts and structures: the distributor of aggressive liquid (1.00), distributor of air 3/2 (2.00) and membrane (3).
The distributor of aggressive liquid (1.00) is made as a united entirety which produced a united compact constitution. Membrane (3), made up of tephlon, are rigidliy connected by the connecting rod (5).
The pump works in the following way: while one of the membranes sucks the aggressive liquids as a result of the under pressure which it produces in its chamber, the other membrane pushes the already sucked liquid with the power of air under the pressure which has an influence from its inside. When the membrane, which sucks in the liquid, touches the micro switch, the role of the membrane is being exchanged. All parts of the chamber are made of materials which are resistent to aggressive liquid. These are tephlon, Koterm and stainless steel.

摘要： Un piston étagé (18) est monté coulissant dans un cylindre (17) de manière à former une première chambre annulaire (24), reliée en permanence à une amenée de fluide primaire sous pression (31, 32), et une seconde chambre annulaire (25) de plus grande section. Une valve de commande (34), avec tiroir à sections différentielles (35), met la seconde chambre (25) en communication alternativement avec l'amenée de fluide primaire sous pression (31, 32) et avec un conduit de retour (40). La valve (34) est pilotée par le fluide primaire, au moyen d'un conduit (47) partant du cylindre (17). Le piston (18) est prolongé par deux plongeurs opposés (19, 20) qui pénètrent dans deux chambres (2, 5) mises en relation avec des arrivées (3, 6) et des départs (4, 7, 12, 13, 14) d'un fluide secondaire.
Application à la fourniture d'eau sous haute pression, pour la foration de roches.
