Pressure operated shut off valve and fluid distribution system comprising such pressure operated shut off valve

A fluid distribution device for a vehicle fluid distribution system, comprising:

• a pressure operated shut off valve comprising
• a valve housing;
• a valve chamber enclosed by the valve housing;
• a first fluid entry port;
• a first fluid exit port;
• a first fluid inlet duct opening into the valve chamber;
• a first fluid outlet duct opening into the valve chamber;
• a first valve body slidably arranged in the valve chamber, the first valve body being held closed against a valve seat and being operable by fluid pressure provided in the first fluid inlet duct and acting on the first valve body to lift the first valve body from the valve seat;
• a selector mechanism comprising a control cam serving as a mechanical stop;
• the mechanical stop selectively blocking or unblocking the first valve body upon actuation;
• wherein the selector mechanism is rotably or slidably arranged in the valve housing or at the valve housing and thereby selectively blocking and unblocking the first valve body depending on a position of the selector mechanism;
• wherein the first valve body is a resilient diaphragm;
• wherein the resilient diaphragm has a cam follower on a side facing towards an inside of the valve chamber;
• a fluid delivery pump;
• a first feed line;
• a plurality of fluid consumers;
• a plurality of fluid delivery lines, wherein each one of the plurality of fluid delivery lines is arrangeable in fluid communication with at least one of the plurality of fluid consumers;
• and
• wherein the first feed line and the plurality of fluid delivery lines are connected by the pressure operated shut off valve.
