.~> Motive fluid constantly applied to one working member face (235) (321) {1}
DEFINITION
Classification: 91/415
(under the class definition) Apparatus in which the motor is provided with opposed working member faces, motive fluid being applied to or evacuated from one of said faces to cause the working member to move in one direction and being applied simultaneously to or evacuated simultaneously from both of said faces to cause the working member to move in the opposite direction or to slow the movement in said one direction.
(1) Note. The opposed working member faces are usually of different areas. However, they may be of the same area with or without an additional impelling force such as a spring applied in one direction.
(2) Note. Opposed working member faces are defined as faces which when motive fluid is applied thereto tend to move the working member or load in opposite directions.

22+, for expansible chamber motors with preliminary admission of motive fluid to a contracting working chamber to cushion movement of the working member and further admission of motive fluid through a different supply path to said working chamber to cause the working member to move in the opposite direction to expand the chamber.
51, for double acting expansible chamber motors having motive fluid constantly applied to opposed working member faces and selectively vented therefrom to cause the motor to move in either direction.
152, for expansible chamber motors of the multiple expansion type. 165, for expansible chamber motors in which motive fluid at different pressures may be simultaneously applied to opposed working member faces.
172, for expansible chamber motors having opposed, relatively movable working members with motive fluid being simultaneously applied thereto.
464, for double acting expansible chamber motors in which motive fluid is supplied to opposed working member faces when the motor is in idle or stationary condition.
