Abstract
A solenoid valve apparatus, for supplying two end-users from a single pressure fluid source, includes two valves and a solenoid apparatus for actuating the two valves. The two valves are installed opposite each other, and the solenoid apparatus is located between the two valves. The solenoid apparatus contains two armatures configured as movable valve elements, which are approximately coaxial with each other. A coil surrounds the two armatures over at least part of their axial extensions. A pressure fluid channel connects the pressure fluid inlet of one valve to the pressure fluid inlet of the other valve. Each valve has a corresponding pressure fluid outlet, which connects to a respective end-user pressure fluid chamber.
