The controller has a dynamic emulation model of a hydraulic driving device, and is constituted to estimate the pressure oil flow rate passing through the relief valve from the emulation model according to the operation amount of the operating lever, and to control the pump flow rate of the pump so that the relief flow rate estimation value gets close to zero. According to this, relief loss can be precisely reduced without generating a response delay or pressure loss, and the power can be saved.

摘要： The crash sensor of the present invention comprises a magnet, a sensing mass made of a ferromagnetic material and attractable by the magnet, a sleeve made of a paramagnetic material and restricting the movement of the sensing mass in one direction, a pair of strips that make a closed circuit by contact with the sensing mass having moved in one direction and a body fitted with the magnet and housing the sensing mass, the sleeve and the contacts; the crash sensor further comprising a magnetic shield made of a ferromagnetic material and covering the magnet and the body. The magnetic shield forms a closed-type magnetic field by covering the magnet and the body and forms an appropriate magnetic loop in the vicinity of the sensing mass, so that the crash sensor also acts as a magnetic shield to protect itself from being influenced by outside ferromagnetic bodies and makes effective use of the magnetic force of the magnet. The above pair of strips are fitted in the same direction vertically on the inner wall of the body, whereby they do not project out in the axial direction so that the crash sensor can be of a reduced whole length, as well as of smaller outside diameter than conventional crash sensor with its contacts positioned facing each other.
