Abstract
A screw rotor pump (10) with drive spindle (18) arranged in a pump housing (12) and at least one sealed spindle (16), which on the intake side is/are arranged by means of a journal-like end (17) in a bearing recess (44) of a pump section, especially a pump cover (20), is to be improved in that on the internally supported screw rotor pump (10) bearing elements (46) are arranged in order to take up the axial thrust of the sealing spindle(s) (16), on which bearing elements the journal-like spindle end and/or a bearing journal (46) are arranged, which receive the journal-like spindle end and/or a bearing journal (17) and are connected to the pressure chamber (15) of the screw rotor pump. In addition the bearing recess (44) for the bearing journal (17) in a bearing bush (46) is proposed as bearing element and this rests in a recess (58a) of the pump cover (20). <IMAGE>
