Abstract:

PURPOSE:To maintain a favorable operating state all the time even in a cold district, etc., by constituting a solenoid valve so as to be opened or closed by means of a pulse, while compensating the pulse width in a manner conformable to oil temperature. CONSTITUTION:An oil temperature detector 23 is installed in a hydraulic circuit, and output out of this oil temperature detector 23 is inputted into a controller 30, then a solenoid valve SV is driven for its opening or closing with pulse width in a manner conformable to oil temperature.
