ABSTRACT:
A device for providing pulsation-free feeding of a liquid medium from a supply container to a consuming device for use in a road-marking machine is disclosed. Two statically-operating reciprocating-piston pumps are arranged between the supply container and the consuming device such that when one pump is on suction stroke, the other is on a feed stroke. The pump flow rate is proportional to the drive speed of the road-marking machine and the feed flow of each pump has zones which overlap the other. The feed sides of the pumps are connected to a change-over means which alternately connects delivery flows from the pumps to the consuming device and also connects the pressure side of the pumps simultaneously to the consuming device and to the supply container, which prevents pressure flow fluctuations as the back-pressure to each pump is the same.
