Abstract

A blow valve comprises at least one blow valve body, an environmentally controlled first receiving space constructed in the blow valve body and having at least one entry opening and at least one exit opening for receiving and conveying an operating gas, and a second receiving space constructed in the blow valve body for the guidance of a pressure distribution member such as, for example, a piston element. A sealing component prevents exchange of gas between the first receiving space and the second receiving space and is arranged between the first and second receiving spaces. The sealing component has a stationary part for fixing to the blow valve body and a movable part for changing the flow rate of the operating gas, wherein the setting member is surrounded in part by the sealing component and is coupled to the movable portion in order to move it.
