ABSTRACT:
A pump has a reciprocably driven rod disposed in a quantity of fluid to be pumped, there being an outlet from the fluid chamber. A pair of elements respectively disposed at the outlet opening and on the end of the rod are separable and jointly define a pumping cavity which is filled when the elements are separated. When the elements are brought together, pumping is achieved in that one of the elements is yieldably compressible so as to reduce the size of the pumping cavity to force out a drop of fluid. A stirrer is disposed near the above-mentioned elements, and reciprocatory motion of the rod is transferred to a one-way clutch to provide incremental rotation of the stirrer.
