FIELD: hydraulic machine engineering. SUBSTANCE: taper roller radial-thrust bearings of drive shaft are installed for axial displacement relative to housing through value of preset mounting clearance Δ, which is automatically compensated for in process of pump operation by follow-up mechanism made in form of plunger installed in housing bore communicating through throttle with delivery line. EFFECT: increased service life of pump and improved operation reliability. 2 cl, 1 dwg
