摘要: A pump apparatus and system wherein a single piston in a single cylinder produces positive pumping action in both of its reciprocating movements into a single-output outlet at one end of said cylinder. A valving system incorporated into the piston itself establishes communication of the pumping medium between one side of the piston and the other within the confines of the single cylinder. Suction of fluid into the cylinder is produced by said piston in one direction only of its rectilinear movement through a one-way valve at the other end of the cylinder. When constructed in conjunction with a vacuum-operated diaphragm for operating the piston, liquid pressure in the cylinder is utilized also to ensure a fluidtight seal between the cylinder and the adjacent vacuum chamber housing the diaphragm.

摘要: A two-stage air powered hydraulic pump has a portion of the air pressure that operates the pump diverted directly to the reservoir. The air pressure on the reservoir presses hydraulic fluid in the reservoir out of the reservoir, through the pumping chamber and to the load to quickly advance the load under low load conditions and to pre-charge the pumping chamber.

摘要: A pump of extremely simple manufacture, requiring no maintenance, is made up of a tubular body (1) closed at each end by end pieces (10a and 10b), orifices (15a and 15b) of which are respectively connected to a pneumatic control circuit (4) and to the circuit of liquid in circulation (3). A piston (2) circulates freely within the tubular body, driven by an overpressure or an underpressure appearing in the upper chamber (17a) and controlled by the pneumatic control circuit. The displacement of the piston brings about the filling and emptying of the lower chamber (17b), thus permitting the pumping of a liquid. This type of pump, of universal use, needs only a connection to a compressor (40) and to a vacuum pump (41) for its running, and these two elements may be common to a great number of such pumps.
