PURPOSE:To make it possible to operate a main piston surely even if there is an inequality in pressure losses, large or small, after each discharging port of a distributing valve by connecting each discharging port of a distributing valve of double pipes type which has plural discharging ports to the supplying port of each distributing valve of single pipe type corresponding to it by a lubricating pipe. CONSTITUTION:When a manual lever 1e is handled by an operator, grease is transferred to a distributing valve 2 through short main pipes A, B and from there distributed to distributing valves 4-7 through lubricating pipes a-d and then supplied from the distributing valves 4-7 to lubricating point 9 through a lubricating pipe 8. Since the indicating bars 2e of a double lines distributing valve 2 are all moved, following the operation of a pump, nearly at the same speed and reciprocated all together, given if there is a clog in lubricating pipes on and after a-d, it can be judged easily because the indication bar 2e doesn't work. The double lines distributing valve 2 can be also arranged in a visible range and moreover the number is small, therefore the movements of all number of indicating bars 2e can be seen easily. |
