Vehicle brake arrangement with rotation pumps has drive shaft extending perpendicularly with respect to direction of gravity, pump output ports extending in opposite direction to gravity

摘要

The brake arrangement has a number of rotation pumps, each with a rotating section with an outer rotor with internal teeth, an inner rotor with outer teeth and a number of distance vol. formed between the engaged inner and outer teeth. A casing (71c,71d) for the rotating section has a suction port (62) via which brake fluid is sucked in, an output port (63) via which brake fluid is output from the rotating section and a casing opening through which a drive shaft (54) for the rotation pumps leads to be coupled to the inner rotors of the pumps. The drive shaft extends perpendicularly with respect to the direction of gravity and the output ports extend in the opposite direction to gravity.
