Abstract
A hydraulic controller includes: a pair of liquid chambers; and an on-off valve capable of opening and closing a flow channel on the side of the liquid chamber with a higher hydraulic pressure out of the pair of liquid chambers. The flow channel can provide communication between the pair of liquid chambers. A baffling device is provided in the liquid chamber with a lower hydraulic pressure, to baffle hydraulic fluid flowing from the liquid chamber with the higher hydraulic pressure. Thus, it is possible to reduce operating noise resulting from operation of the on-off valves.
Claims9
A hydraulic controller comprising:
- a pair of liquid chambers;
- and
- an on-off valve capable of opening and closing a flow channel on the side of the liquid chamber with a higher hydraulic pressure out of the pair of liquid chambers, the flow channel being capable of providing communication between the pair of liquid chambers,
- wherein a baffling means, which opposes the on-off valve, is provided in the liquid chamber with a lower hydraulic pressure out of the pair of liquid chambers, to baffle hydraulic fluid flowing from the higher-pressure liquid chamber into the lower-pressure liquid chamber.
