DEFINITION

Classification: 415/152.1

Motor runner with selective inlet paths for reversible rotation:

(under subclass 151) Device wherein working fluid* adds energy to and rotates the runner* (i.e., "motor*" runner). The vane* or other (control) means varies the route of working fluid flow to the runner to rotate the runner unidirectionally in one direction when the vane or other (control) means is in one position and to rotate the runner unidirectionally in an opposite direction when the vane or other (control) means is in another position.

SEE OR SEARCH THIS CLASS, SUBCLASS:

61, for a device having means controlling working fluid to one of a plurality of runners which are on separate shafts* or mounted for relative rotation.

82, for a motor runner device motivated by a reaction-type jet discharge nozzle from an internal working fluid conduit which has means for controlling the runner directions.

85, for a device having a runner with annular blade rows or fluid channels spaced on a common radial plane which has means for reversing the runner's rotation.

167, for a device with a movable working fluid pipe or nozzle which is capable of directing working fluid to a runner from various directions.

910, for a device reversible between pump and motor use which may have means for reversible rotation of the runner.

911, for a device comprising a reversible pump runner and separate outlets for opposing directions of rotation.
