Abstract:
1. A device for a dispensing valve in a pipe, the pipe being connected, when in its position of use, to a receptacle containing a fluid at a pressure (P 3 ), in which the valve comprises: an activating element; a sealing element which is force-transmittingly connected to the activating element; and a valve seat against which the sealing element seals when the valve is inactive and in its position of rest; in which the pipe at least is open in a first end and contains at least: a separate pressure balancing channel communicating only with the ambient pressure (P a suction channel communicating with the first end of the pipe and with the valve, and which is closed at a second end of the pipe; and said activating element in the form of a flexible membrane attached internally in the pipe, and which separates the pressure balancing channel from the suction channel; in which the valve is arranged to open to fluid outflow when the suction channel, via the first end of the pipe, is supplied an underpressure (P wherein the opposite long sides of the membrane are attached to the inside of the pipe and at a distance from each other; wherein the lengthy sealing element is force-transmittingly connected to the lengthy membrane via a lengthy and axially extending first valve rib attached to the membrane and projecting outward therefrom; and wherein the lengthy valve seat communicates with the pipe via a lengthy and axially extending second valve rib attached to the inside of the pipe and projecting outward therefrom; whereby an internal fluid outflow channel, which is open at the second end of the pipe, is defined between the membrane, the inside of the pipe and said two valve ribs.
