Abstract (en)
[origin: WO2015011384A1] The invention relates to a rotary-oscillating subassembly (1) for volumetrically pumping a fluid, comprising a hollow body (2) defining a cavity (10) through the wall of which two pipes (11, 12) pass, a piston (3) defining, together with said cavity (10), a work chamber (31) and comprising a groove (22) leading longitudinally into said work chamber (31), said piston (3) being angularly movable such as to put said work chamber (31; 131) in fluid communication with one, then neither, then the other one of said pipes (11, 12; 111, 112), and alternately movable in longitudinal translation so as to cause the volume of said work chamber (31) to vary, and consecutively to then deliver said fluid, said piston (3) having a seal (32, 33, 34) formed by at least one sealing bead (32), a sealing half-bead (33), and at least one sealing tab (34) longitudinally connecting said sealing bead (32) to said sealing half-bead (33).
