Abstract (en)
[origin: EP1138947A2] The pump has a casing with a drive shaft through it and with a suction channel, outlet channel, flow regulating valve and flow limiting valve. The cover has a control plate on the casing side and an end plate on the other side. The casing and endplate have slots (9) preventing the slide lifting off the cam ring at low revs. The casing slots have a recess (11) enabling the region behind the rollers to be filled if rollers (10) are used.
