DEFINITION

Classification: 91/330

(under subclass 218) Apparatus in which means are provided to (1) move a distributor independently of motor operation or (2) adjust movement of a distributor relative to the movement of the working member either independently of or in response to a condition of motor operation.

(1) Note. This definition includes any means to cause or permit the adjustment of the distributor such as a relatively adjustable joint or connection.

39+, for independent distributor actuation for cyclic control.

187+, for relatively movable working member with means interconnecting working members to cause relative motion in which means is provided to vary cyclic relation of distributor to working member.

247+, for timing control for a cyclically operable motor by relative adjustment of plural movable fluid control elements. 277+, for adjustable working member reversal position for a cyclically operable motor.

282+, for fluid supply through diverse paths to cyclically operable working member controlled distributor motor chamber, which paths may be independently controllable.

284+, for independent means to adjust the distributor motor supply or exhaust passage of a working member controlled distributor of a cyclically operable motor.

289+, for adjustable means to retard or lock a cyclically operable, working member controlled distributor motor.

478, for motors having three or more cylinders arranged in parallel, radial, or conical relationship with a rotary transmission axis and in which there is provided separate motive fluid control for each working chamber and means for varying the cyclic members and its associated control valve.

482+, for motors having three or more cylinders arranged in parallel, radial, or conical relationship with a rotary transmission axis and means for varying the cyclic relation between at least one of said reciprocating members and its associated control valve.
