Title:
車両用液圧制御装置
Document Type and Number:
Japanese Patent JP4285139
Kind Code:
B2
Abstract:
A solenoid cover includes a solenoid valve housing chamber housing solenoids of solenoid valves that project outwards from a hydraulic unit and a lower space therebelow. Two labyrinth portions with a fluid passage formed by a plurality of partition plates and communication holes are provided so as to be symmetrical with each other in a left-right direction below the lower space. An air vent communicates with the outside and which serves as a water drain is provided below each labyrinth portion. When a pressure in the solenoid valve housing chamber becomes negative due to a temperature decrease, water flows through the air vent at a high flow rate. Then, the water entering through the upper communication hole flows down along the partition plate toward the lower communication hole, which easily enables the water to be drained to the outside.
