Document Type and Number:
WIPO Patent Application WO/2017/110611
Kind Code:
A1
Abstract:
The purpose of the invention is to suppress an increase in temperature of a control device for a supercharger and to increase the life of the control device for the supercharger. This work machine is a work machine comprising a variable-capacity supercharger in which the boost pressure is changeable, and a work device. The work machine comprises: a variable-capacity working hydraulic pump that is driven by an engine, and that supplies pressure oil to an actuator which drives the work device; a supercharger control device that controls the supercharger; a temperature detection device that detects the temperature of the supercharger control device; and a main control device that limits the maximum absorption torque of the working hydraulic pump when the temperature of the supercharger control device is higher than a first temperature compared to when the temperature is lower than the first temperature.
