Rotational vibration type sub-assembly and rotational vibration type positive displacement pumping device for pumping a fluid into the positive displacement

摘要

A rotational vibration type subassembly for positive displacement pumping of the fluid (1), a hollow body defining a cavity (10) having two ducts (11, 12) pass through the wall and (2); action a chamber (31) cooperating with said cavity (10) to define a piston comprising a channel (22) which opens in the longitudinal direction in said working chamber (31) in (3), the working chamber ( 31; 131), said duct (11, 12; 111, 112) at least one was in fluid flow communication with, then not communicated with any communication, then it is possible move at least angularly so as to other things and communicated Further, the changing the volume of the working chamber (31), continuously movable in the longitudinal direction translation for reciprocal to suction and then discharging the fluid, at least a sealing ring (32), sealed stop half-ring (33), and said at least one sealing gasket formed from the sealing strip (34) connecting the longitudinal sealing ring (32) in the sealing half-rings (33) (32, 33 It carries a 34), and a piston, rotary vibrating subassembly.
