Abstract
A bleed device for hydraulic circuits and a kit for bleeding are described that enable bleeding of the hydraulic circuit independently of the removal or slackening of the bleed device. In one embodiment, the bleed device comprises two opposing ends having a bleed duct extending through them. One end is designed to close the aperture of the hydraulic circuit. The other end is part of a quick-release connector and is designed to couple with the other part of the quick-release connector, whereby the bleed device may be connected to a bleed liquid collection vessel. Also, coupling of the quick-release connector simultaneously opens a one-way check valve in the bleed duct. The one-way check valve closes during normal operation of the hydraulic circuit. A protective cap on the bleed device keeps foreign matter from fouling the quick-release connector end.
