Abstract
A valve arrangement having electromagnetic actuation and valve elements that can be displaced by the effect of a solenoid acting against the force of a closing spring whereby the valve elements close in a sealing manner or open between valve seats of varying cross sections provided between the delivery passage and the discharge port. The first valve element (4) cooperates with a valve seat (3) having a large cross section and the first valve element (4) is provided with a passage (6) in the space upstream from the first valve seat (3) to a second valve seat (7) of smaller cross-sectional dimension whereby the second valve seat (7) cooperates with the second valve element (8) so that actuation can be simplified at reduced size and control of the valve elements can be designed in a simpler manner to be less susceptible to malfunctioning.
