Abstract
Improvements in valves for fluids, characterized in that in a roughly hollow cylinder-shaped passage box, with seating surface for a preferably conical closure body, a working cylinder is connected to the housing by radial ribs, in whose chambers of work discharge conduits for the pressure agent leading through the box, and whose working piston supports the closure body on its plunger rod.
