BRAKE DEVICE FOR VEHICLE WITH ROTARY PUMP DEVICE
Document Type and Number:
Japanese Patent JP2011105206
Kind Code:
A
Abstract:
To eliminate the need to dispose a damper as a member separate from a rotary pump device, and to suppress enlargement of a size.
A second port 81 and a fourth port 83 are used as delivery ports, and a space formed between an end surface of an insertion direction front side of a first cylinder 71a and a bottom surface of a recessed part 101a and a space formed between a third cylinder 71c and a fourth cylinder 71d are used as dampers. Therefore, the damper as the member separate from the rotary pump device can be dispensed with. Accordingly, compared to the case where the damper is provided as the separate member, enlargement of the size can be suppressed, and a number of parts can be reduced.
