摘要:
A quick coupling device including a snap-fastening finger (16) for engaging a portion (26) of a suitable complementary structure, and a tab (30) rotatably mounted on the finger (16) to unmask a stud (42) when the coupling device is incorrectly coupled to the complementary structure (14). The invention is particularly suitable for quick couplings for pipes and ducts as used in the car industry.
摘要:
A bypass valve device in particular for a fluid circuit, in particular for a liquid circuit associated with a heater, the device being suitable for being interposed between the fluid inlet and outlet tubes or hoses of the heater. The device is constituted by a unit assembly shaped to provided two passages (24, 30) for the fluid and interconnected by said valve (13), the unit assembly being embedded, preferably by overmolding, in a plastic material or an elastomer material (40) similar to that of the hoses or compatible therewith.
摘要:
The fluid tank is divided by a planar partition (3) into a fluid inlet compartment and a fluid outlet compartment. Toward the outside, the fluid tank has an annular protruding rim (19) surrounding two openings (1, 2), one for each of the two compartments. A coupling device case en bloc including inlet and outlet pipes for the fluid, which are placed facing the openings (1, 2), is provided with centering means cooperating with the rim (19).

A rapid connection fluid coupling is disclosed, for connecting a first end piece, to which a cooling liquid flow duct or pipe of a motor vehicle engine is fixed, to a second end piece of a testing circuit, heater unit or other vehicle element. The first end piece has a perforator for a closure positioned in the end piece prior to filling the engine with the cooling liquid. The closure comprises a seal with a membrane made from an elastomer material, such as rubber or other similar material, having the general form of a cup with a bottom having weaker zones for tearing the cup after perforation at its center. The zones are formed as a star with radiating arms whose ends are on a circle which defines an annular zone with the periphery. The free end of the lateral wall of the membrane is molded on a frame with an L shaped half cross section and has at least one and preferably two peripheral lips oriented from the end towards the bottom while diverging with respect to the lateral wall. When the two end pieces are interconnected, the second end piece drives the closure into engagement with the perforator to perforate the closure and allow fluid flow through the end pieces.
摘要:
An assembly device for a heat exchanger and tubular connector assembly, in which the tubular connector opens out into an opening in a tank of the heat exchanger and is fixed firstly to a flexible hose by a permanent connection and secondly to the tank via an easily disassembled resilient connection, with sealing between the tubular connector and the tank being provided by an elastomer ring which is radially compressed therebetween. The tubular connector and the tank are in alignment along an assembly axis and they constitute two parts to be assembled by snap fastening at least one axially-directed tab carried on one of the two parts. The tab is radially resilient and is provided with a snap-fastening catch which engages axial abutment means carried by the other one of the two parts. The tab has an expansion spring configuration whose resilient reaction acts radially in the direction tending to maintain the tab pressed against the abutment means when the said two parts are in the assembled position. The spring-forming tab is in the form of a leaf spring comprising at least a first branch and a second branch substantially parallel to each other and to the assembly axis, with the first branch projecting from one of the two parts in the assembly direction while the second branch projects from the axially inner end of the first branch in the opposite direction to the assembly direction, such that the spring-forming tab is generally U-shaped, with the catch projecting radially outwards from the second branch of the tab.
摘要:
The invention relates to the manufacture, by molding, of a joining and connecting block between main ducts made from elastomer material and branch ducts which are connected thereto. The block may be molded in a single piece in two mold parts assembled together along a joining surface in the form of a Z.
摘要:
The fluid tank includes two coaxial necks. The inner neck is defined by a longitudinal portion of a partition that also includes at least one transverse portion dividing the fluid tank longitudinally into two chambers for the inlet and outlet of fluid. A rapid coupling device cast en bloc includes two coaxial necks cooperating respectively with the necks of the fluid tank, to couple the chambers to an external circuit.
摘要:
Purge branch coupling for a main flexible hose, reinforced or not, sheathed or unsheathed, of the type having the shape of a tubular insert which is intended to co-operate with a closure piece of its proximal extremity and which is integral with the main hose by moulding coating of a splicing material, particularly comprised of plastic or elastomer material. According to this invention, the tubular insert forming the purge branch coupling comprises a plurality of openings provided in its tubular wall so that the coating of said junction material, which penetrates into said openings during moulding establishes linking bridges between the portions of said coating which envelope the insert, thus providing for the holding in position of said insert. Application for couplings in lines of water, air and fuel circuits in motor vehicles.
摘要:
A quick action coupling is disclosed for connecting simultaneously at least two pipes or hoses to the water box of a radiator or to the inlet and outlet members for the cooling fluid of a motor vehicle engine, said water box or said members comprising a generally cylindrical shaped chimney and n ways (n being a whole number at least equal to two) which open into said chimney, said coupling comprising n rigid conduits whose outlets into said connector are of a shape and position mating with the outlet orifices of said corresponding ways in the chimney of the water box or of said members so as to form n fluid circuits, as well as seals for sealing between the different fluid circuits with respect to each other, comprising: a male connector of a form mating with said chimney; and sealing of said circuits with respect to the outside is provided by a single additional seal whatever the number n of circuits.
