DEFINITION

Classification: 91/341

(under subclass 218) Apparatus in which means transmitting cyclic motion from the working member to the distributor includes an element which moves relative to the working member and extends into the working chamber.

SEE OR SEARCH THIS CLASS, SUBCLASS:

276, for cyclically operable motors in which the distributor forms a traversed, movable portion of the working chamber side wall, the distributor being usually reversed by contact with the working member.

313, for cyclically operable motors having a working member controlled motive fluid supply for a distributor motor in which a pilot valve actuator extends into the working chamber.

348+, for motors in which the working member includes spaced working surfaces, and in which the distributor actuating means includes a member contacting the working member and movable relative thereto and positioned between said spaced working surfaces.
