392  DF  WORKING MEMBER POSITION RESPONSIVE MOTIVE FLUID CONTROL {9}
393.~ Position initiated timing or delay means


DEFINITION

Classification: 91/393

(under subclass 392) Apparatus in which in response to the position of the working member means are actuated which cause a predetermined delay or time to elapse prior to control of the motive fluid.

(1) Note. The operation of the timing or delay means is initiated in response to the position of the motor working member, but thereafter the amount of time delay which occurs before the motive fluid is controlled is not dependent upon the operation of the motor.

SEE OR SEARCH THIS CLASS, SUBCLASS:

35+, for expansible chamber motors having timing, delay, pattern or cyclic control means which are operated independently of the motor, i.e., not initiated by the motor.

218+, and especially subclasses 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.
