Definitions

  • the present invention relates to an enclosure containing a pressurized liquid, a pressurized liquid supply assembly and a method for bleeding a hydraulic brake circuit.
  • CH-A-533 045 describes an enclosure for liquid of the type comprising a neck, the free end of which is provided with an orifice for the flow of the liquid contained in the enclosure, closed by a perforable seal to release the liquid.
  • US-A-5 186 370 discloses an enclosure of the same type which may contain a pressurized liquid.
  • the invention particularly aims to allow a single operator to conveniently perform the bleeding of a hydraulic brake circuit for a motor vehicle.
  • the invention relates to an enclosure containing a liquid of the aforementioned type, characterized in that the liquid is a brake fluid for a motor vehicle under pressure.
  • the invention also relates to an assembly for supplying a hydraulic circuit with pressurized liquid comprising an enclosure as defined above, characterized in that it further comprises means for connecting the neck of the enclosure to a pipe for supplying pressurized liquid to the hydraulic circuit, provided with means for piercing the cover that can be actuated after connection of the neck to the supply pipe.
  • connection means comprise a connection intended to be screwed in a leaktight manner on the neck, and a plunger-punch mounted to slide in leaktight manner in the connection between a waiting position and a position for piercing the cover, provided with a channel, one end of which is connected to the supply duct and the other end of which opens out in line with the neck of the enclosure, this latter end comprising a projection for piercing the cover.
  • the invention also relates to a method for bleeding a hydraulic brake circuit comprising a brake fluid reservoir and bleeding orifices, characterized in that the reservoir is supplied with pressurized brake fluid with an assembly as defined above, in which the enclosure contains the brake fluid under pressure, so as to pressurize the hydraulic brake circuit, and that the flow of brake fluid is monitored by the open bleeding orifices .
  • FIG. 1 shows an enclosure for pressurized liquid according to the invention, designated by the general reference 10, comprising a metal body 12, of generally cylindrical shape, provided at one end with a bottom 14 and at the end opposite from above 16.
  • the bottom 14 and the top 16 are fixed to the rest of the body 12 by known means, for example by crimping.
  • the body 12 of the enclosure has two internal compartments 18, 20 separated by a piston 22 mounted to slide axially inside the body 12.
  • the compartment 18, delimited between the bottom 14 and the piston 22, is filled with a pressurized gas of known type.
  • the compartment 20, delimited between the top 16 and the piston 22, is filled with a liquid usually used in hydraulic brake circuits, for example mineral oil.
  • the piston 22 tends to impose on the liquid contained in the compartment 20 a pressure of a few atmospheres.
  • the enclosure 10 is filled with pressurized gas and with liquid by known means.
  • the gas filling means comprise an orifice 23, formed in the bottom 14, closed by a plug 23A made of elastomer.
  • the top 16 of the enclosure body has a neck 24 extended by an externally threaded neck 26.
  • the free end of the neck 26 has an axial orifice 28 closed by a cover 30 preferably made of a complex material comprising an aluminum layer coated with a polyethylene layer.
  • the cover 30 is heat-sealed on the free end of the neck 26, by known means, which makes it possible to ensure a sealed connection between the neck 26 and the cover 30 resistant to the pressure of the liquid contained in the compartment 20.
  • a protective cap 32 is screwed onto the neck 26.
  • the assembly 34 comprises an enclosure 10 as shown in FIG. 1, the protective cap 32 having been removed from the neck 26, and means 36 for connecting this neck to a flexible conduit 37 for supplying the hydraulic circuit with liquid under pressure, this circuit not being shown in the figures.
  • connection means 36 comprise a sleeve 38 forming a connection comprising an end 38A internally threaded, intended to be screwed on the neck 26, and another end 38B reamed forming a guide for a plunger-punch 40 of generally cylindrical shape, mounted to slide axially in the fitting 38 between a waiting position, as shown in FIG. 2, and a position for drilling the cover 30, as shown in FIG. 3.
  • the internal surfaces of the two ends 38A, 38B are separated by an annular shoulder 42 forming a support for an annular seal 44 interposed between this shoulder 42 and the free end of the neck 26.
  • the punch-punch 40 is pierced axially with a channel 46 for connecting the neck 26 to the flexible conduit 37.
  • the end of the channel 46 opening to the right of the neck 26, internal to the fitting 38, is extended by a pointed projection 48 intended to pierce the seal 30.
  • the end of the channel 46 opposite the neck 26, external to the fitting 38, forms a nozzle 50 intended to be fitted into a corresponding end of the flexible conduit 37, the seal between this conduit and the nozzle 40 being ensured by a clamping collar 51.
  • the seal between the internal surface of the end 38B of the connector and the plunger-punch 40 is ensured in particular by an O-ring 52 disposed in an annular groove 53 formed in the plunger-punch 40.
  • the plunger-punch 40 is actuated by a thrust disc 54 fixed by known means on the external part to the connector 38 of this plunger-punch.
  • the punch-punch 40 is positioned in the standby position by complementary shoulders 56 formed on the surfaces in contact with this punch-punch and the connector 38.
  • the punch-punch 40 is held in the standby position by means elastic of known type, not shown in the figures.
  • the protective cap 32 is removed from the neck 26 and the connector 38 is screwed onto the latter, then the end opposite the connector 38 of the flexible conduit 37 is connected in a manner known per se to a brake fluid reservoir to which conventionally connected the hydraulic brake circuit. Then, actuate the pusher-punch 40 by pressing on the disc 54 so that the projection 48 pierces the cover 30, as shown in FIG. 3. After drilling the cover 30, the brake fluid under pressure contained in the enclosure 10 flows through the orifice 28 of the neck 26, the channel 46 and the flexible conduit 37 so as to supply the brake fluid reservoir and put the hydraulic brake circuit under pressure.
  • a single operator can simultaneously pressurize the hydraulic brake circuit by actuating the ram plunger 40 of the assembly 34 and monitor the bleeding orifices of the hydraulic brake circuit disposed at the vehicle brakes.
