Abstract
A fluid-pressure transmitting apparatus that is capable of securing the operationality of a working machine and braking and preventing against engine stall. The apparatus can switch between a working-machine operating device and a traveling operating device. When a second operating unit is operated during operation of a first operating unit, the pilot pressurized oil outputted from each operating means through first and second pilot-pressure admission passages is admitted to a low-pressure selecting valve. At this time, the pilot pressurized oil is automatically selected through the low-pressure selecting valve to control the delivery capacity of the traveling pump and braking and preventing engine stall and realizing travel at low speed.
