  • Publication number: 20150135704
    Abstract: A brake fluid reservoir includes in its upper portion a bottleneck with a thread and a top for receiving a cap with an edge and a top. The top of the bottleneck has channel opens into the atmosphere, one end of the channel leading into the atmosphere, one end of the channel leading into the interior of the bottleneck and the other end communicating with the outside atmosphere via a cavity.

  • Patent number: 8667793
    Abstract: Reservoir in which the walls (111, 121) and the partitions (112, 122) are assembled by thermowelding the edges together with the exception of the edges (113a, 123a) of the well elements (113, 123), the edge (113a) of the upper element (113) and the edge (123a) of the lower element (123) of the well (104) have complementary shapes producing, by assembly under the pressure exerted by bringing together and welding the walls (111, 121) and the partitions (113, 123) of the reservoir (100), a fluid-tight joint between the edges of the two well elements, without generating projections that are deformed toward the interior of the well. The thermowelding hotplate (140) has a cut-out (143) along the line of the well elements (113, 123) so as to leave the edge (113a, 123a) of the well elements out of contact when the edge (111a, 121a) of the walls (111, 121) and that (112a, 122a) of the partitions (112, 122) of each of the reservoir parts (110, 120) is pressed against one face (141, 142) of the hotplate.

  • Patent number: 8197012
    Abstract: A device for supplying a downstream hydraulic brake fluid to a hydraulic brake circuit of a motor vehicle equipped with a clutch includes an enclosure intended to contain the hydraulic fluid, the enclosure being provided with at least one outlet nozzle and with an inlet orifice. The enclosure forms a downstream portion of a reservoir, the reservoir comprising an upstream portion forming an upstream enclosure intended to collect an upstream hydraulic fluid from the clutch of the vehicle. The upstream enclosure 4 includes at least one inlet nozzle serving to transfer the upstream hydraulic fluid toward the upstream enclosure 4. The inlet orifice is an intermediate orifice whereby the upstream enclosure opens into the downstream enclosure, the intermediate orifice being equipped with a means for filtering the upstream hydraulic fluid.

  • Publication number: 20060038441
    Abstract: A connection device for a brake fluid reservoir intended to link an outlet (10) of a brake fluid reservoir (1) to the supply inlet (20) of the primary circuit and to the supply inlet (21) of the secondary circuit of a master brake cylinder (2) or to two supply inlets (40, 41) of a manifold device (4) mounted on the said supply inlets of the master cylinder. A pipe system (3) has a main pipe (30) to which two branch pipes (31, 32) are connected. The main pipe (30) has an inlet end (33) connected to the outlet of the brake fluid reservoir and each branch pipe has a supply end (34, 35) that is connected to a supply inlet (20, 21) of the master cylinder or to an inlet (40, 41) of the manifold device (4).
