.~ Changeable from multiple expansion to simple operation
DEFINITION
Classification: 91/11
(under subclass 6) Apparatus comprising two or more expansible working chambers having, in one condition of operation, interconnecting passages whereby a prior one of the chambers receives motive fluid and then exhausts the motive fluid into the subsequent chamber for expansion therein; and wherein additional passage means is provided, in another condition of operation, for introducing motive fluid from the source to the subsequent chamber, the subsequent chamber then receiving no fluid from the first chamber.
(1) Note. This definition does not include motors in which motive fluid is supplied to a first expansible chamber and then directed to a second expansible chamber while the first is still in communication with the supply so as to in effect provide direct communication between the second chamber and the supply.
SEE OR SEARCH THIS CLASS, SUBCLASS:
8+, for expansible chamber motors of the multiple expansion type wherein motive fluid may optionally be supplied directly to a subsequent working chamber in addition to fluid supplied thereto from a prior working chamber.
