Abstract
A valve provided with a passage for conveying a medium, the passage having at least a first closable aperture, and with a closing device that is suitable for closing at least the first aperture. The valve is provided with a holder element that is movably included in a holder element house chamber of the holder element house. The closing device is capable of being supported by the holder element or forms an integrated part of the holder element, and the closing device is controllable by the medium. The holder element is controllable, only by the medium, for releasing at least the first aperture by means of the closing device.

A valve provided with a passage for conveying a medium, the passage having at least a first closable aperture, and with a closing device for closing at least the first aperture, the valve being provided with a holder element that is movably included in a holder element house chamber of a holder element house, the closing device being supported by the holder element or forming an integrated part of the holder element, wherein the holder element is controllable, only by the medium, for releasing at least the first aperture by movement of the closing device.
A valve provided with a passage for conveying a medium, the passage having at least a first closable aperture, and with a closing device for closing at least the first aperture, the valve being provided with a holder element that is movably included in a holder element house chamber of a holder element house, the holder element house chamber being in fluid communication with a part of the passage by means of a passage duct and the holder element being controllable by the medium and capable of being brought, only by the medium, into contact with the closing device for releasing at least the first aperture.
In a milking installation comprising a vacuum conduit and a vacuum pump, a valve located between the vacuum conduit and the vacuum pump, the valve comprising:
- a passage in fluid communication with the vacuum conduit;
- a valve seat located within the passage;
- a valve element located within the passage and having a first position in which it engages the valve seat to close the passage and having a second position in which it disengages the valve seat to open the passage;
- a holder element mounted to engage the valve element and support it in its second position and being movable to allow the valve element to move to its first position;
- a pressure responsive member operatively mounted to cause the movement of the holder element;
- and
- a fluid connection between the pressure responsive member and the vacuum conduit such that the pressure responsive member is exposed to a pressure within the vacuum conduit.
