<P>PROBLEM TO BE SOLVED: To provide a hydraulic control unit capable of optimizing the flow of a pressure medium around a piston pump without further working the inside of an open hole of a housing. <P>SOLUTION: The hydraulic control unit includes: the open hole 31f formed on the housing 30; the piston pump which is accommodated in the open hole 31f and forcibly feeds the pressure medium; a pump closing cover 55 which tightly closes the piston pump into the housing 30 and guides the pressure medium; and a channel 11b which is formed in the housing 30 so as to receive the pressure medium flowing out of the pump closing cover 55. The pump closing cover 55 is provided with a plurality of outer circumferential groove parts 55b in order to cause the pressure medium to flow through the channel 11b from an inner part of the pump closing cover 55. <P>COPYRIGHT: (C)2013,JPO&INPIT |
