Hydraulic unit

Abstract

A hydraulic unit, comprising a tank case for accommodating a hydraulic medium, in which a hydraulic pump is disposed and is adjoined by a valve block on which at least one controllable valve is arranged in a supply line to a hydraulic user, and an electric motor which has a stator housing on the side of the valve block that is opposite the tank case, and the shaft of which is coupled to the hydraulic pump via the valve block, characterized in that the valve block and stator housing are integrally formed.

1 . A hydraulic unit, comprising a tank case for accommodating a hydraulic medium, in which a hydraulic pump is disposed and is adjoined by a valve block on which at least one controllable valve is arranged in a supply line to a hydraulic user, and an electric motor which has a stator housing on the side of the valve block that is opposite the tank case, and the shaft of which is coupled to the hydraulic pump via the valve block, characterized in that the valve block ( 18 ) and stator housing ( 10 ) are integrally formed. 
   
   
       2 . The hydraulic unit according to  claim 1 , characterized in that the valve block, on its side facing the tank case ( 26 ), has an axial annular collar which engages the interior of the tank case ( 26 ) in an approximately fitting manner while the end of the tank case ( 26 ) that faces the valve block ( 18 ) engages a recess at the outside of the annular collar ( 26 ), causing the outsides of the stator housing and tank case to be approximately flush with each other. 
   
   
       3 . The hydraulic unit according to  claim 1 , characterized in that the valve block ( 18 ) and stator case ( 10 ) are formed from a cast metal.
