Patent ID: 8197012

Claim:
Device ( 1 ) for supplying a downstream hydraulic brake fluid to a hydraulic brake circuit of a motor vehicle equipped with a hydraulically controlled clutch, comprising an enclosure ( 2 ) to contain said hydraulic fluid, said enclosure ( 2 ) being provided with at least one outlet nozzle ( 20 ) supplying said hydraulic brake circuit, and with an inlet orifice ( 21 ) allowing said downstream hydraulic fluid to be introduced into said enclosure ( 2 ) so as to compensate for any loss or consumption of said downstream hydraulic fluid in said hydraulic brake circuit, characterized in that: a) said enclosure ( 2 ) is a downstream enclosure ( 2 ′), forming a downstream portion ( 30 ) of a reservoir ( 3 ), said reservoir ( 3 ) comprising an upstream portion ( 31 ) forming an upstream enclosure ( 4 ), to be supplied with an upstream hydraulic fluid from the clutch of said vehicle, b) said upstream enclosure ( 4 ) comprises at least one inlet nozzle ( 40 ), said inlet nozzle ( 40 ) to transfer said upstream hydraulic fluid from said clutch toward said upstream enclosure ( 4 ), c) said inlet orifice ( 21 ) is an intermediate orifice ( 21 ′) whereby said upstream enclosure ( 4 ) opens into said downstream enclosure ( 2 ′), said intermediate orifice ( 21 ′) being equipped with a means ( 5 ) for filtering said upstream hydraulic fluid so as to continuously convert upstream hydraulic fluid into downstream hydraulic fluid devoid of solid particles for supplying said hydraulic brake circuit, d) said filtration means ( 5 ) forms a composite filtration element ( 5 ′) comprising a peripheral portion ( 50 ) assembled in a sealed manner to a container body ( 4 ′, 4 ″) and surrounding a central opening, and a filtering central portion ( 51 ) secured to said peripheral portion ( 50 ) and covering the entire central opening, said peripheral portion and said filtering central portion ( 51 ) covering said intermediate orifice ( 21 ′).
