Reciprocating Pumps - an overview ScienceDirect Topics

Reciprocating pumps use a piston moving back and forth in a cylinder (see Fig. 23.16).Two check valves for the input and output at one end of the cylinder allow one-way flow; this gives a pulsed output. Because rotational motions of engines are not easily converted to reciprocating motions, this type of pulp is seldom used on mobile equipment.

Reciprocating Piston Compressor - an overview ...

Reciprocating piston compressors can be classified into several types. One type is the trunk or automotive piston type (see Figure 3-2).The piston is connected to a connecting rod, which in turn is connected directly to the crankshaft. This type of compressor has a single-acting cylinder and is limited to refrigeration service and to smaller air compressors.
