Publication number: 20020139435Abstract: An attachment (3) for a vacuum gun (2), for evacuating and containing a fluid from a reservoir of fluid, such as brake fluid from a brake system. The attachment (3) has a body (21, 25) with an inlet (22) for the fluid and an outlet (24) that may be sealingly attached to a front end of a gun (2). The attachment (3) also has a coupling (26), a container (27) which is releasably attachable to the coupling (26), a first passage (33, 34) extending between the inlet (22) and the container (27), a second passage (35, 36) extending between the container (27) and the outlet (24), and a tap (70) which may be moved to either close or open the said passages (33, 34, 35, 36). In use, the gun (2) generates a vacuum within the attachment (3) and when the tap (70) is in the open position, the fluid may be collected within the container (27). A float valve (83) within the second passage (35) ensures that the container (27) cannot overfill with fluid.Type: ApplicationFiled: October 11, 2001Publication date: October 3, 2002Inventors: David Mitchell, Alan Grieves
