Provides is a device for metering and measuring quantities of fluids, especially in a liquid fuel pump, with several volume meters, to each of which is allocated an upstream valve, and a liquid supply branching off into individual line opening into the valves, in which the valves (5) and the volume meters are fitted in a block-shaped housing (1, 2, 3) having an inlet aperture (4) and supply channels (6) branching off to the valve (5) and forming the individual supply lines. A first housing block (1) comprises the inlet aperture (4) and valve connection apertures (8) each covered by a valve head (7), a supply channel (6) opens into each of said valve connection apertures (8), a connection channel (10) closable by a piston (9), a disc, a diaphragm or the like of a valve (5) running from said supply channel (6) to the volume meter concerned. The volume meters are separately allocated to as second housing block (2, 3) and every other housing block (2, 3) forms the rotor housing for two mutually engaging worms (11, 12) of a worm meter through which liquid can flow axially. The faces (2', 3') of the second housing blocks allocated to the axial bearings (13, 14) of the worms cover apertures (15) in the connecting channels.
