Abstract: An assembly for perfecting the distribution of fluids in multiple conduits intended for the distribution of a main circuit in multiple secondary tubular circuits, it comprises multiple modules 4, 10, 5 linked together by double male bayonet connections. The modules all have the same female orifices, occupied by male bayonets 7h all identical and of the same dimension extended at their other end by connections 7 for tube 12. Male bayonet plugs 3, with their bayonets 3h and taps 6 bearing identical male bayonets 6h may also occupy any of the female bayonets of the distribution module.The invention is used for the distribution of water and in particular in the building industry for use with sanitary and heating water.

Abstract: Rotary switching connectors providing both connection of the pipes with each other or to fixed members and for establishing the flow of fluid from the ones to the others or interrupting said flow by closing off the upstream circuits and venting the downstream circuits to the atmosphere. They are formed of two coupled elements 1 and 2 able to be manually rotated with respect to each other about an axis XX and to keep the position which is given them. An inlet channel 4 in element 2 and an outlet channel 3 in element 1 each equipped with an integrated connector 66 and 55 open into their respective adjacent faces over the same circle of radius XY. The angular registration of these orifices allows the sealed bidirectional passage of the fluid of the device by means of a seal 8 housed in a cup 7 at the periphery of channel 4 and compressed between the two elements 1 and 2.

Abstract: The invention relates to a compressed fluid saving device positioned between the outlet of a distributor and the admission of a pneumatic jack. The device comprises a valve which is kept open, to allow the flow of driving fluid into one chamber of the jack from the start and right through the stroke, by the exhaust back-pressure escaping from the other chamber of the jack, and acting on the piston of said valve. When the back-pressure disappears, the valve closes under the action of a screw-adjustable spring.

Abstract: The invention relates to a pressure relay comprising inside its body, and besides a distributor device with a pressure inlet, an outlet and an exhaust, an auxiliary conduit of large cross-section which is connected with a control input of the said distributor device and comprises means to mount the said body on the jack, and to receive a pipe fitting supplying pressure to a jack.The invention finds an application for signalling the outermost positions of a jack piston, or in combination with branch-pipe type jacks.

Abstract: A gasket disposed between a coupling for a pipe conveying high pressure fluid and an apparatus presenting a tapped hole in which the threaded part of the coupling is screwed, said gasket comprising a hoop made of hard, resistant material bearing by one of its two faces against the wall of the apparatus and presenting a bore in which are engaged, around the coupling, a seal member made of creepable, malleable material and a ring to be crimped made of ductile material having a wedge-shaped cross section, said ring being crimped inside the hoop when the coupling is screwed. The invention provides tightness of couplings screwed on an apparatus.

Abstract: The present invention relates to instant fittings for smooth, bare tubes, comprising a hollow body having a bore corresponding to the section of passage of the fluid and an inner housing in which is disposed the tube retaining means, said tube being held by an obturation and abutment means, mounted on the body at one of the ends of the housing on the side of the entry of the tube in the fitting. The housing which presents at least two successive bores encloses a locking element and a tube retaining member generally tubular in form, which are mounted to slide axially in said housing, said retaining member and said locking element comprising click means ensuring a tightening stress of the retaining member on the tube. The invention is used for the connection of tubes.

Abstract: A valve that is connected to a container of pressurized fluid and has a spring-loaded striker member which is normally secured in a ready position out of contact with a seal retaining the fluid within the container, the striker member being releasable by the action of a releasable lock for movement by a loading spring into an operate position in which the striker member perforates the seal to release the pressurized fluid. The lock is responsive to a control member to lock the striker member against movement when the control member is in a non-operating position, and to release the striker member upon arrival of the control member at an operating position. Movement of the control member is effected by a releasable connector which connector is further responsive to the arrival of the control member at the operating position to then release the cable allowing the escape thereof.
