F04B9/123 - CPC Classification

Classification description:

Piston machines or pumps characterised by the driving or driven means to or from their working members the means being fluid the fluid being elastic, e.g. steam or air having only one pumping chamber

Sub-classes:

F04B9/1235 » {the movement of the pump piston in the two directions being obtained by two single-acting piston fluid motors, each acting in one direction} 6
F04B9/125 » reciprocating movement of the pumping member being obtained by a double-acting elastic-fluid motor 37
F04B9/127 » rectilinear movement of the pumping member in the working direction being obtained by a single-acting elastic-fluid motor, e.g. actuated in the other direction by gravity or a spring 27
