<P>PROBLEM TO BE SOLVED: To provide a hydraulic control device, miniaturizable even when having a jet pump. <P>SOLUTION: This hydraulic control device 100 is constituted of an upper valve body 2, a lower valve body 3, and a separator plate 4 sandwiched by the upper valve body 2 and the lower valve body 3. The hydraulic control device 100 forms the jet pump 1-1 having a delivery oil passage 21 formed in the upper valve body 2, a suction oil passage 31 formed in the lower valve body 3 and communicating with the delivery oil passage 21 via a suction communicating hole 42 formed in the separator plate 4, a high pressure oil passage 32 formed in the lower valve body 3 and supplying a hydraulic fluid of higher pressure than pressure of a hydraulic fluid in the suction oil passage 31, and a high pressure communicating hole 41 formed in the separator plate 4 and communicating the high pressure oil passage 32 with the delivery oil passage 21. <P>COPYRIGHT: (C)2009,JPO&INPIT |
