.~.~ Controlled by separate relatively movable valves
DEFINITION
Classification: 91/244
(under subclass 236) Apparatus in which a plurality of exhaust flow paths are each controlled by a different valve, said valves being movable to cyclically control fluid flow through the different flow paths, and also being relatively movable.

237+, for cyclically operable expansible chamber motors having multiple exhaust passages controlled by separate relatively movable valves, in which the relatively movable valves comprise a movable exhaust valve having a relatively movable valve controlling a second exhaust passage therein.
240+, for cyclically operable expansible chamber motors having multiple exhaust passages controlled by separate relatively movable valves, in which the valve for a second exhaust passage is fluid pressure actuated.
242, for cyclically operable expansible chamber motors having multiple exhaust passages controlled by separate relatively movable valves, in which the valve for a second exhaust passage is controlled by exhaust pressure.
