A cylinder is installed within a case, and an output shaft and an arm that is integrated thereto and extends in a radial direction are installed within the cylinder. A piston extending in an arc slides and is displaced in a circumferential direction of the cylinder within the cylinder. One end portion of the piston is rotatably connected to the arm. The cylinder is internally provided with a first pressure chamber in which the arm is housed and a second pressure chamber in which the other end portion of the arm is slidably installed. A pressure medium is fed into one of the first and second pressure chambers and discharged from the other, and the output shaft pivots in a rotational direction.

| 12 | Volumetric metering pump | US3612729D | 1969-03-28 | US3612729A | 1971-10-12 | COMMARMOT ROGER |
| The specification describes a volumetric metering pump for accurately dosing very small quantities of liquid, in which two pistons are arranged to extend in opposite directions, and are interconnected by a crossmember. Small pulse jerks are simultaneously applied to each piston, so that one piston draws liquid into its cylinder and the other expels liquid from its cylinder. A slide valve is provided firstly to direct liquid from an inlet duct to one cylinder and to an outlet duct from the other cylinder. At the end of the stroke this situation is reversed.

| A reciprocating piston of a positive displacement pump has a piston body with a plurality of cooling fins on one or more exterior surfaces of the piston body. A seal coupled to the piston body forms a seal with the walls of a cylinder in the positive displacement pump. A rod moves the piston within the cylinder to cause the displacement of fluid. | ||||||

| A plunger and cylinder assembly for the fluid end of a reciprocating pump. The assembly comprises a traveling cylinder, a stationary plunger, and an optional sleeve secured to the traveling cylinder in a detachable manner. The traveling cylinder is displaced along its axis by a thrust component and acts cooperatively with the stationary plunger to create a pressure change in the reciprocating pump. | ||||||
