DEFINITION

Classification: 91/263

(under subclass 252) Apparatus in which the inlet valve is cyclically moved to control the flow of motive fluid to the working chamber by working member controlled actuating fluid, and means are provided to adjust the control of the inlet valve actuating fluid so as to vary the time of closing of the inlet valve.

SEE OR SEARCH THIS CLASS, SUBCLASS:

247+, for cyclically operable expansible chamber motors having independent inlet and exhaust valves each movable about an axis in which there is provided means to adjust relatively adjustable fluid control elements to vary the timing of fluid control events, especially subclasses 252+

for such motors which include adjustable plural control element inlet valves to vary the timing of the cut off element, and subclass 261 for such motors which include a biased inlet valve movable about an axis and provided with adjustable trip means to vary the timing of the fluid control event.

255, for cyclically operable expansible chamber motors having adjustable fluid control for a fluid actuated cut off element of a plural fluid control element inlet valve, so as to vary the time of occurrence of the cut off event.

266, for cyclically operable expansible chamber motors employing oscillating working members and which may include valves which move about an axis.

281+, for cyclically operable expansible chamber motors having working member controlled motive fluid supply for operating a distributor motor, other than those which adjust timing of fluid control events as defined under subclass 247. 352, and see the subclasses there noted for other distributors movable about an axis.
