摘要： A hydraulic pump includes a hydraulic motor (2) and an impeller (3). The impeller (3) produces a first axial force (Fi) into a first axial direction. The hydraulic motor (2) is a gear pump including gears with helical teeth (4a, 4b). The gear with helical teeth (4a, 4b) produces a second axial force (Ft) into a direction opposite in relation to the first axial direction. The second axial force (Ft) produced by the gear with helical teeth (4a, 4b) is utilized to compensate the first axial force (Fi).

摘要： Here, an apparatus for mixing pressurised fluid and an additive is presented. The apparatus (2) includes an inlet (5) for the feed-in of pressurised fluid, an additive container (10a, 10b) and an outlet (6) for the output of the mixture of the pressurised fluid and the additive. The pressurised fluid is divided into a part conveyed to the additive container and a remaining part. The additive container (10a, 10b) is pressurised and additive is conveyed from the additive container (10a, 10b) into connection with said remaining part to form a mixture of the pressurised fluid and the additive, which mixture is conveyed to said outlet (6). The apparatus includes at least two additive containers (10a, 10b). By a valve arrangement (14), the additive is fed alternately from different additive containers (10a, 10b) into connection with the pressurised fluid.

摘要： Shock absorber used for damping a control flow which is to be directed to the control valve belonging to a hydraulic system or is to be directed to the adjustable valve of the flow through which absorber the flow of the hydraulic fluid can be directed at least in one direction. The absorber is a stopper which restricts the run of the flow to be damped which stopper is equipped with one or several ducts which let the flow go through the mentioned stopper when the other orifice of the mentioned duct is blocked with a plate in such a way that bending of the mentioned plate opens access for the flow through the mentioned stopper due to the pressure of the flow coming along the mentioned duct.
