    • By disposing various current-sensing layers on a semiconductor element with a current-sensing function, wherein signals corresponding to the sensing currents derived from each current-sensing electrode are inputted independently into said over-current control circuit and short-circuit control circuit in a control circuit for said semiconductor element; or by constructing the current-sensing resistor in said control circuit with various resistors connected in series, wherein a single sensing current flows into this resistor to generate various detection voltages divided by the resistor, while detection voltages with different values are inputted independently into said main current turn-off command circuit and main current control circuit the value I.sub.oc of the over-current detection level for the semiconductor element with a current-sensing function and the value I.sub.sct at the short-circuit current detection level can be set independently of each other. Therefore, while increasing I.sub.oc, setting I.sub.sct within a short-circuit current withstand capacity of the semiconductor element, and extending the upper limit in the main current of said semiconductor element, it is possible to avoid element break-down due to a short-circuit current.

    • The invention allows securing greater discharge pressure and flow rate at high revolutions of an engine in order to secure lubrication and cooling, while reducing discharge pressure and flow rate at low and medium revolutions of the engine in order to improve efficiency. The invention includes a housing; a relief valve; a valve passage; a main discharge flow channel; a main relief flow channel; an auxiliary relief flow channel; a solenoid valve mounted on the auxiliary relief flow channel; and a spring. The solenoid valve is controlled so as to switch between communication and shut-off between the auxiliary relief flow channel and the large-diameter passage section in accordance with an increase or decrease in engine revolutions, and oil in the large-diameter passage section is discharged when the shut-off is implemented.
