FIELD: machine building.
SUBSTANCE: invention relates to machine building and can be used for stepless control over volume and pressure of pumped fluid. Hydraulic pump comprises cylinders with pistons arranged parallel with and around drive shaft, crankcase with drive shaft, on which ring is pivotally connected to it with possibility of joint rotation and change of inclination angle. Said swash plate is connected via radial bearing and communicated with pistons by connecting rods. Fixation of swash plate from joint rotation with shaft is carried out by link installed on axis, made on swinging washer and moving along slot in housing. Adjustment of inclination angle of swinging washer is performed by wedge moving on key slot of drive shaft by means of action on wedge by screw mechanism.
EFFECT: improving operating reliability of hydraulic pump and improving its functional characteristics, as well as reducing overall dimensions and weight.
