Abstract
The present invention relates to an oil pressure control apparatus which comprises an oil pressure pump, a pressure regulating valve in a first oil line and a drain valve in a second oil line. A supply valve is provided upstream of the drain valve in the second line for minimizing the oil pressure loss as much as possible, and for providing a short response time upon actuation.
