Title:
FLUID PRESSURE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP3716813
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a fluid pressure control device whose size is made smaller to easily secure its mounting space, while securing reliability by means of a simple arrangement and reducing the number of part items.
SOLUTION: An ECU 62 and a solenoid valve 20 are positioned on a plurality of stages, so the size of a hydraulic module 1 is made smaller to easily secure the mounting space. Thus, the fluid pressure controller can be easily mounted in a limited space within an oil pan to provide the effect of facilitating assembly and maintenance operations. Heat generated by the ECU 62 is transferred to a valve body 30 from a substrate adhesion plate 64 via a barrier rib 35 and hydraulic fluid discharged from the solenoid valve 20 is splashed to the plate 64 to release heat from the plate 64 to the hydraulic fluid. In this way, the ECU 62 can be cooled efficiently without requiring such a member as a cooling fan, and reliability is secured by means of a simple arrangement while reducing the number of part items.
