Document Type and Number:
Japanese Patent JPS5629087
Kind Code:
A
Abstract:
A pump for pumping low viscosity fuels has a cam defining a pumping chamber bore wall. A plurality of slippers define pumping pockets located within the bore wall. The slippers are rotated through inlet arcs and through outlet arcs. A pair of orifices of predetermined diameter are located in the respective inlet arcs and communicate with each pumping pocket at a location radially inwardly of the slippers.
