  • Patent number: 10280526
    Abstract: A system that produces a sterilizing solution, has an electrolytic cell containing an anode compartment and a cathode compartment separated by a porous ion-exchange membrane. The system further has an ion-exchange water softener arranged to supply the electrolytic cell with deionized water and a brine tank arranged to supply the electrolytic cell with a sodium chloride brine solution. The system is arranged for conducting a regeneration of the water softener by use of a sodium chloride brine solution from the brine tank. The system has a positive displacement pump controlled by a control unit of the system to selectively supply a sodium chloride brine solution from the brine tank to the electrolytic cell and to the water softener for regeneration thereof.

  • Patent number: 5947003
    Abstract: A hydraulic piston machine is disclosed, having a piston arranged to move back and forth in a cylinder body. In such a machine it is desirable to be able to achieve a longer service life, even when the hydraulic medium is not suitable for lubricating the bearing faces. For that purpose, at least on its outer face sliding on the cylinder body, the piston has a layer of a friction-reducing plastics material, wherein at the end of the piston there is provided a bearing face of an articulated joint by means of which a slide shoe is connected, articulated to the piston, the layer being continued onto the bearing face.

  • Patent number: 5762477
    Abstract: A piston/slide shoe arrangement of a hydraulic piston machine is disclosed having a slide shoe in connection with a piston (4), with a friction reducing plastics material there between, wherein the plastics material, forming channel, extend into a through opening in the slide shoe in a direction towards a sliding contact surface of the slide shoe. The sliding contact surface in operation lies against a swash plate. The slide shoe and the plastics material are provided outside the through-opening with at least one connecting element which takes up the shear forces between the slide shoe and the plastics material.

  • Patent number: 5758566
    Abstract: A piston with a slide shoe is described for a hydraulic piston engine, where the piston is designed with a ball socket, and where the slide shoe is provided with a corresponding ball head, whereby these are connected in a ball-and-socket joint, and where the ball head of the slide shoe is designed as a unit moulded into the ball socket in friction reducing material so that the ball head is captured in the ball socket. Hereby an improved fixation of the moulded-on all head on the slide shoe is achieved.

  • Patent number: 5752428
    Abstract: A hydraulic axial piston motor (1) is disclosed, having a cylinder drum (4) which is connected, so that it is non-movable axially, to a shaft (3) and so that they rotate together, and which has at least one cylinder (5), for each cylinder a piston (6) arranged in the cylinder, which piston bears at its end projecting from the cylinder drum (4) against a swash plate (8) via the intermediary of a slider shoe (7), a pressure-applying arrangement (9) for holding at least one slider shoe (7) against the swash plate and a control plate (12) with control kidneys. It is desirable for such a motor to be reliably operable even when the shaft is provided with axial play. Leakages in particular are to be avoided. For that purpose, the pressure-applying device (9) is mounted so as to e axially movable relative to the cylinder drum (4).

  • Patent number: 5730043
    Abstract: A hydraulic axial piston motor is disclosed, having a rotatable cylinder drum, in which several work pistons, each provided at one end with a slider shoe, are arranged in work cylinders so as to be axially movable, having a control plate, a swash plate, against which the slider shoes bear, a pressure plate which holds the slider shoes on the swash plate, and a pressure-applying unit, which acts on the pressure plate and comprises a hydraulic piston-cylinder arrangement. Using such a motor it is desirable for an adequate contact pressure to be produced using simple means. For that purpose, the piston-cylinder arrangement is arranged between the cylinder drum and the control plate.

  • Patent number: 5716142
    Abstract: A radial journal bearing (5, 6) is indicated, with an interior bearing surface placed facing an exterior bearing surface, where one of the bearing surfaces comprises a slide shoe (7, 8), which has one end with a contact face loaded to contact against the other bearing surface, and where this end is movable in such a manner that the contact against the other bearing surface can be maintained by a relative displacement of the bearing surface at right angles to the direction of the load. Hereby it is achieved that the variation of the leakage between the slide shoe and the opposing bearing surface is essentially reduced, resulting in longer life and greater stability.

  • Patent number: 5685215
    Abstract: A hydraulic piston engine driven by a lubricant-free, water-based pressure fluid, and comprising an enclosing housing and a piston-connected drive shaft supported by radial journal bearings in bearing bushings. One of the sliding surfaces of the radial journal bearing comprises a recess with a bearing-supporting hydrostatic pressure fluid pocket. The center of the recess is displaced by an angle (.alpha.) in the direction against the direction of rotation of the drive shaft, seen in relation to the geometrical, radial mean point in the high-load area for transmission of the piston forces to the bearing surface via the drive shaft. Hereby a particularly reliable piston motor of the type indicated is provided.
