Abstract
Abstract A solenoid valve includes a carrier which is slidably mounted in a valve sleeve and which has an entirely closed first chamber and an adjacent second chamber. A tube attached to the carrier and passing through the first chamber, maintains continuous communication between the second chamber and the interior of the sleeve. The first chamber accommodates a solenoid armature; the second chamber houses a valve ball. Behind the valve ball the second chamber is in continuous communication with a space containing a valve seat. The second chamber has a wall portion which defines an opening oriented towards the valve seat and which retains the valve ball that partially projects through the opening for cooperation with the valve seat. The valve ball is urged against the wall portion by a spring.
