Abstract
A pump for distributing water at an extremely high-pressure to several appliances. Every appliance can connect and disconnect independently and has associated with it a device that diverts the water trapped in it when it disconnects. The object is to minimize wear in the water-diversion device. The device accommodates a constricted section in the form of an annular space that the water trapped in the appliance can escape through. Such pumps are employed for cleaning a wide range of articles.
