.~> Double acting motor reversed by pressure variation of motive fluid
DEFINITION
Classification: 91/165
(under the class definition) Apparatus in which the motor is provided with opposed working member faces, motive fluid being applied to said faces at the same or different times, the motive fluid which is applied to one working member face being above atmospheric pressure and the motive fluid which is applied to the second face also being above atmospheric pressure, but being at a different pressure than that applied to the first face.
(1) Note. The opposed working faces may be on different, interconnected, relatively movable working members or may be integrally connected together. Opposed working faces are defined as faces which when motive fluid is applied thereto
tend to make the working member move in opposite directions when the faces are integrally connected. When the working faces are relatively movable the application of motive fluid to the opposed working faces tends to move the power output member in opposite directions.
(2) Note. This definition does not include those devices in which a different pressure is obtained in the opposed chambers merely because a flow of the motive fluid occurs as, for example, where a pressure drop occurs due to flow past a restriction but which would disappear when flow ceases.

6+, and especially 28+, for expansible chamber motors in which motive fluid at different pressures is applied to the same working chamber at different times.
152+, for expansible chamber motors of the multiple expansion type. 415+, for expansible chamber motors in which motive fluid at the same pressure is simultaneously applied to opposed working member faces.
