  • Air operated radial piston and diaphragm pump system
    Patent number: 6547537
    Abstract: Three or more diaphragm pumps (12,14,16) are interconnected to sequentially receive an activation fluid from corresponding piston and cylinder pumps (18,20,22) synchronized by a control mechanism (24) which includes a distributor plate (42) with directive shallow slots (80,82,84) for conduiting activation fluid to a porting plate (44) and via openings (60,62,64) to the piston and cylinder pumps (18,20,22).

  • Control for reciprocating pumps or the like
    Patent number: 4085655
    Abstract: A control valve for alternately applying fluid pressure to two drive members of a reciprocating work device such as a pump. A valve piston is slideable in a closed cylinder to which pressurized fluid is transmitted. The valve piston, controls the fluid depending on the position of the piston in its cylinder, to pressurize one chamber and vent the other so as to move the work device in one direction or the other. In turn, the work device controls the fluid to position the valve piston.
