Abstract
PURPOSE: To rapidly operate motor stopping means, by providing the first pressure transmitting means, transmitting control pressure in accordance with main pipe line pressure, and the second pressure transmitting means, transmitting control pressure in relation to input means of oil hydraulic motor control means.
CONSTITUTION: When a control lever of a servo valve 10 is returned to its neutral position, a selector valve 13, operated interlocking to the servo valve, is also returnd to its neutral position, and a pipe line to an open-close valve 21 is communicated to a tank. However at this time, pressure at the suction side of an oil hydraulic pump 1 rapidly rises to operate a control valve 11, then the servo valve 10 can not be reset to its neutral position and remains in a state of selecting position. Here a selector valve 14 is opeated in accordance with pressure in a main pipe line released from a shuttle valve 12. Accordingly, when an oil hydraulic motor 2 becomes a substantially stopping state, the selector valve 14 is reset to the neutral and the selector valve 13 is also in its neutral position, then the open-close valve 21 is operated, thus the main pipe line can be placed in a non-conductible state.
