The pressurization device is located completely outside the second reservoir, and has a volume that is variable between two positions: a deployed position, in which the volume of the pressurization device is maximal, and a folded position, in which the volume of the pressurization device is minimal. | 12-10-2015 |
20150352474 | QUICK CONNECT FILTERS AND FILTER ASSEMBLIES - Quick connect mechanisms between a fluid filter and a head that permits quick connection/disconnection between the two. The mechanisms clamp the filter shell in place with a plurality of radially displaceable locking elements. When the filter is inserted into the head, an element that controls the radial displacement of the locking element is rotated to radially displace the locking elements and lock the shell in place. External sealing is achieved by the means of suitable sealing elements, for example a compression face seal and/or a radial O-ring seal. The clamping force comes from the rotation of the control element to a lock position which displaces the locking elements in a radial direction to a lock position. When the control element is rotated to an unlock position, the locking elements are free to move or are actuated to an unlock position, allowing the filter to be removed. | 12-10-2015 |
