Document Type and Number:
WIPO Patent Application WO/1999/049247
Kind Code:
A1
Abstract:
An apparatus provided in a pipe connecting a hydraulic fluid source and a device using the hydraulic fluid for controlling the supply and cut-off of the hydraulic fluid supplied from its source to the device. This apparatus is provided with a housing (1) comprising an inlet passage (2) connected to the hydraulic fluid source, an outlet passage (3) connected to the device, and a drain passage (4) open to the air. In this housing (1) is provided a three-way two-position selector valve (5) capable of switching between a supplying position for cutting off the outlet passage (3) from the drain passage (4) and allowing it to communicate with the inlet passage (2) and a cut-off position for allowing the outlet passage (3) to communicate with the drain passage (4) and cutting off it from the inlet passage (2). This three-way two-position selector valve (5) is operated between the supplying position and the cut-off position by a control lever (15) one of whose ends pivots on the housing (1).
