Abstract
The invention in question relates to a metering device for fluid metering pumps of the type composed of a piston member sliding inside a hollow body with which valve means for drawing in and discharging the fluid are associated. The piston member is actuated by a connecting-rod/crank mechanism which is associated with a gearmotor group. The device in question is characterized by the fact that the valve means consist of an umbrella valve which is made of rubber or equivalent material, with an elastically deformable cap and a tubular body provided with a spout-type nozzle having elastically deformable lips. The valve is fixed with its body onto the end section of the said hollow body. <IMAGE>
