FIELD: engines and pumps.SUBSTANCE: pump comprises housing with first and second working fluid inlet and outlet made in the wall and circular channel made inside rotor body. Circular channel features constant cross-section, and has openings ion the wall and working fluid suction-displacement pistons. Said pistons are engaged with drive shaft via propeller shaft of asynchronous transmission of irregular revolution of pistons. Rotor is engaged with drive shaft, circular channel being aligned with rotor rotational axis and divided into two semi-channels by radial webs. Every said semi-channel is divided by said piston into fore-piston and aft-piston chambers if seen in direction of piston stroke. Every piston is connected with irregular revolution shaft arranged in rotor axis and engaged with asynchronous transmission propeller shaft and rotor with drive shaft. Fore-piston chamber has fore-piston opening in rotor wall nearby web while aft-piston chamber has aft-piston opening in rotor wall nearby the web. Rotor wall with said openings abut on to slide over housing wall with openings into first and second manifold. First manifold communicates with first opening while second manifold communicates with second opening.EFFECT: swinging feed of fluid into external pipeline.2 cl, 56 dwg |
