Control unit for controlling a pressure build-up in a pump unit

摘要: The invention relates to a control unit ( 4 ) for controlling the pressure buildup in pump 2 ), with valve 5 and actuation 6 connected it, wherein is embodied as an I-valve that opens inward flow direction, which has body 11 supported so it can move axially housing 12 of rests against seat 13 from inside when closed. In order produce whose requires lower forces short switching times, proposes characterized by means effective surface such way forces, act on closed are due present cancel each other out.
