DEFINITION

Classification: 91/35

(under the class definition) Apparatus including means separate from the motor to (1) cause or permit the motor to operate or not to operate for a period of time and then act to start, stop or change the mode of operation of the motor; or (2) cause the motor to operate through a given reciprocating cycle of operation repetitiously; the operation of said means being independent of and not controlled by the

operation of the motor or a pressure or flow condition of the motive fluid supplied to or exhausted from the motor and not requiring the intervention of a human operator.

(1) Note. The means is not considered to be independent of the motor and is not included under this definition if its operation is initiated by the motor.

(2) Note. The means separate from the motor may not be another motor which produces power for external use such as the first stage of a multiple expansion engine.

152+, for expansible chamber motors of the multiple expansion type.

170+, for expansible chamber motors having multiple working members one of which acts as or controls the valve means for the other. 218+, and especially 219, 282+, 284+, and 289 for cyclically operable expansible chamber motors including means to delay the shift of a distributor after initiation of the shift by the working member.

364, for expansible chamber motors having feedback control and means to delay operation of the valve means in response to the feedback signal from the motor working member.

393, for expansible chamber motors having position initiated timing or delay means for controlling motive fluid.
