摘要
A rotary reciprocating subassembly (1) for pumping fluid comprising: a hollow body (2) having two ducts (11, 12); And a piston defining a working chamber (31) in cooperation with said hollow body (2)The piston moves angularly between two fluid flow and transition forms and translationally reciprocates to change the dimension of the working chamber 31,Characterized in that the ducts (11,12) are longitudinally offset from one another and the pistons (3) are longitudinally open to the working chamber (31), the pistons (3) are longitudinally offset, In a fluid flow configuration, a pair of side recesses (22, 23), arranged in radial direction, are arranged so that only one of the recesses (22, 23) is in hindrance flow communication with only one of the ducts Includes open channels (25).;
