Bleed device and kit for hydraulic circuits

A kit for bleeding an hydraulic circuit, comprising:

• a quick release connector;
• and
• at least one bleed device, the bleed device comprising:
• a device in which extends a bleed duct, the device including a first end and a second end opposite to the first end, the first end being capable of closing an aperture of the hydraulic circuit,
• a one-way check valve provided in the bleed duct, the one-way check valve being normally closed with respect to an exterior of the hydraulic circuit and being capable of being opened independently of one of a removal and a slackening of the device in the aperture, and
• a quick-release connector arrangement at the second end for use with a quick-release counter arrangement of the quick-release connector, wherein the quick-release connection arrangement is capable of forming a coupling with the quick-release counter arrangement in order to connect the bleed duct to a bleed liquid collection vessel and to achieve a simultaneous opening of the one-way check valve;
• and
• a protective cap capable of being received at the quick-release connection arrangement, and
• wherein the quick-release connector includes a quick-release counter-arrangement and a rod to act on the one-way check valve, wherein the rod acts to open the one-way check valve when the quick-release connection arrangement and the quick-release counter arrangement are coupled.
