F01B11/004 - CPC Classification

Classification description:

Reciprocating-piston machines or engines without rotary main shaft, e.g. of free-piston type in which the movement in the two directions is obtained by two single acting piston motors, each acting in one direction

Sub-classes:

F01B11/006 » {one single acting piston motor being always under the influence of the fluid under pressure} 3
F01B2011/005 » {with oscillating pistons, i.e. the pistons are arranged in ring like cylinder sections and oscillate with respect to the center of the ring} 1
