The valve device is connected to a pressure source in a housing (1,37,9). A first valve (51,47,48) is arranged as an intake valve (51,47). Also arranged is an outlet valve (48,47). A piston (35,31) is connected to the first valve and comprises an active surface limiting the outlet of the pressure chamber (3). The piston will open the intake valve following actuation of a control unit (28). Once the control unit activates the piston which actuate the intake of the first valve, a second valve (15) is activated in the housing. |
