摘要
The invention relates to a dosing pump (1) especially for a product which is to be pumped and dosed and has a more or less pasty, especially heterogeneous and fragile, consistency, comprising, along an axis (6): a cylinder head (7) having a circular cylindrical transfer chamber (10), a suction opening (8) and a discharge opening (9) in the same axial position, radially staggered in relation to each other; a mobile suction and discharge piston (12) that can be axially slid in relation to the cylinder head (7), by driving means (13), between a proximal position and a distal position wherein its head (14) is respectively essentially at least in and at least out of the chamber (10); and a circular cylindrical revolving dosing and transfer valve (15) that can be rotatably displaced in relation to the cylinder head (7), between its functional angular positions, said valve comprising a recess (18) having an end opening (19) adjacent to its free end edge (17) and a peripheral opening (20) that can communicate with the suction opening (8) in the suction position, and with the discharge opening (9) in the discharge position. The peripheral opening (20) has a U-shaped, square
