The screw i.e. bleeder screw (2), has an internal space (16) closed at one end and opened at another end of the screw. A duct traverses a wall of the screw and emerges into the internal space of the screw. The duct is formed by a radial bore (15) in the wa...

A method for controlling a valve (14) having large and small orifices (18,16) so as to prevent the valve (14) from switching to the small orifice (16) when a high build gradient is required. The method includes briefly bleeding off a small amount of fluid ...

The coupling is attached to a nipple (5) to allow filling or bleeding of a hydraulic system. It comprises a tubular housing (1) with a connector (6) at one end. The housing contains a sealing ring (2) and the coupling is pushed on until the tip of the nipp...

A hydraulic pump unit (1), for a vehicle, that is unusually capable of precise and effective bleeding, comprises a reservoir (2) for the brake fluid, a master cylinder (3) in the said pump connected to the said reservoir, and a bleed circuit (15) connected...

A bleed device (10) for hydraulic circuits (2), particularly for brake circuits, comprises a plug designed to be fitted with its first end (13) closing an aperture (3) of the said circuit, and a bleed duct (12) extending in the said plug, and is characteri...
