DEFINITION

Classification: 415/20

(under subclass 13) Apparatus comprising a control for the amount of working fluid flowing in a confined path and for adjusting the position of another element or part which does not affect such amount.

(1) Note. The amount of fluid flowing may be controlled by a valve in the supply line, in a relief or bypass line, or in the discharge line or tailgate.

(2) Note. Shifting the direction of discharge of the motive fluid, or imposing a deflector element in the path of the free jet, is not considered to be a control for the amount of motive fluid flow.
