ABSTRACT OF THE DISCLOSURE A dispensing pump is adapted for pressure filling and includes a fluid filling passage which remains sealingly closed during pumping operation by the provision of an annular valve skirt in sealing engagement with a wall of the fluid filling passage, such skirt inwardly flexing during charging the container permitting the charged fluids to by-pass the valve and enter the container. The valve skirt depends from either the plunger head or from the plunger. When depending from the plunger, the valve skirt functions as a guide element for the plunger head together with a plunger head retention bead which cooperates with a pump body retention bead in limiting the upward movement of the plunger head to a predetermined extent. These guide members serve to isolate the plunger against the influence of lateral or eccentric forces applied against the plunger head during its reciprocation. And, the plunger may be capped with a wall surface defining a complementary contour to that of the upper end of the piston which it faces to facilitate expelling of product from the accumulation chamber after the end of the plunger downstroke as this surface first bottoms against the upper end of the piston.
