F01B11/00 - CPC Classification

Classification description:

Reciprocating-piston machines or engines without rotary main shaft, e.g. of free-piston type

Sub-classes:

F01B11/001 » {in which the movement in the two directions is obtained by one double acting piston motor} 41
F01B11/004 » {in which the movement in the two directions is obtained by two single acting piston motors, each acting in one direction} 15
F01B11/007 » {in which the movement in only one direction is obtained by a single acting piston motor, e.g. with actuation in the other direction by spring means} 37
F01B11/009 » {in which the movement in two directions is obtained by two or more double acting piston motors} 1
F01B11/02 » Equalising or cushioning devices 24
