DEFINITION

Classification: 91/331

(under subclass 330) Apparatus in which a mechanical means connects the working member to the distributor, and the mechanical means is manipulated or adjusted to move or control movement of the distributor.

SEE OR SEARCH THIS CLASS, SUBCLASS:

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

277, for a cyclically operable motor having means to adjust the working member reversal position, and which generally involves an adjustment of the motion transmission from the working member to the distributor.

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 relation between at least one of said reciprocating 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. SEE OR SEARCH CLASS

74, Machine Element or Mechanism,

828+, for an alternating motion driven device with means operable during operation to adjust length of and/or displace stroke, and including many such devices which are described as operating expansible chamber motor valves.
