FIELD: engines and pumps.SUBSTANCE: engine comprises cylinder and piston fitted to reciprocate inside said cylinder. Not here that said piston divides said cylinder into first chamber with first port to receive fluid into said first chamber and second chamber with second port to receive second fluid in second chamber to displace said piston. Said first fluid is forced as first set of pulses while second fluid is forced as second set of pulses. Said sets make differential pulsed effects to make said piston displace and to displace, at least, one position pickup arranged in said air engine to read out piston position. Proposed control over air engine is based on position of piston.EFFECT: fast and efficient control.17 cl, 13 dwg |
