PNEUMOHYDRAULIC MOTOR Russian patent published in 1998 - IPC

FIELD: rotary-action drives of various machines. SUBSTANCE: air motor has working chambers connected to the crankshaft and cases through taper rings, on which the ends of the gas-distributing shafts kinematically links through connecting rods to additional crankshafts are fastened through bearings; the gas-distributing mechanisms are located in the working chambers and made in the form of rotors with grooves and stators; the stators have holes communicating with pipelines on which forward and return motion pedal-controlled cocks are installed, these cocks communicate with the atmosphere through an another pedal-controlled cock and through gas pressure regulators communicating with low- and high-pressure cylinders. The crank rotors through bearings are connected to the cases fastened to which by means of pipes are the stators; the pipelines running from the forward and return motion cocks have branches in the form of pipelines on which shut-off cocks are installed, and on the pipeline running from the pedal-controlled cock connected to the atmosphere with its other end a solenoid-operated valve is installed, this valve has an electrical conductor, whose other end is connected to the power source via switches. EFFECT: improved design. 3 wdgr
