Abstract: A control plate (1) of a hydraulic machine having a core (2) is disclosed, which at least on its upper side (O) lying in operation against a cylinder drum is covered with a layer of a friction-reducing plastics material (3) and which has at least two control openings. In a control plate of that kind, it is desirable to simplify manufacture, during which subsequent machining is effected after the plastics material has been moulded on. For that purpose, the plastics material (3) is joined to the core (2) by means of at least one connecting element (8) which, as a result of interlocking engagement with the plastics material (3) and/or the core (2), takes up tensile forces substantially at right angles to the upper side (O).

Abstract: A hydraulic piston machine (1) is disclosed, having a piston arranged to move back and forth in a cylinder body (2). 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 siliding on the cylinder body (2), the piston (4) has a layer (11) of a friction-reducing plastics material, wherein at the end of the piston (4) there is provided a bearing face (12) of an articulated joint (7, 8) by means of which a slide shoe (6) is connected, articulated to the piston (4), the layer (11) being continued onto the bearing face (12).

Abstract: A piston with a slide shoe for a hydraulic piston engine, where the slide shoe comprises a ball socket, and where the piston is arranged with a corresponding ball head, whereby these are joined in a ball-and-socket joint, and where at least partially the ball head is constituted of a spherical surface of a friction reducing material moulded onto and retained in relation to the piston. As a consequence of the subsequent shrinking of the moulded-on, friction reducing material, a possibility is obtained of good fixation of the ball head on the piston, while at the same time a gap can be created between the ball socket and the ball head.

Abstract: A hydraulic axial piston machine is described, having axially movable pistons, which at one end bear by means of slider shoes against a slanting plate, and having a pressure plate (10) for holding the slider shoes in contact with the slanting plate. Under certain operating conditions the slider shoes have a tendency to tilt and lift away from the slanting plate at one side. To prevent this, the pressure plate (10) acts only on a part lying, in the radial direction of the slanting plate (7), outside a predetermined region (28).

Abstract: A method for achieving a specific temperature behaviour of adjusting elements, operating in dependence on temperature, of valves or thermostatic apparatus is disclosed, and also an adjusting element, operating in dependence on temperature, of valves or thermostatic apparatus. Such adjusting elements work in many cases by means of pressure from a pressure chamber, which is provided with a liquid-gas filling. This filling is in many cases toxic or environmentally harmful, in order to achieve satisfactorily the desired temperature behaviour. In order to be able to use also non-toxic and environmentally harmless substances, the pressure chamber is filled with a zeotropic mixture of at least two substances. The ratio of component substances is set in dependence on the desired temperature behaviour.

Abstract: Motorised head pulley (1) comprising a rotating drum (4), which is driven by a permanently mounted hydraulic motor (1a) situated in the pulley (4). Between the motor (1a) and the pulley (4), a reduction gear (2) is inserted. The motor (1a) and the reduction gear (2) comprise moving parts (3, 12, 14, 15), which are designed for operation in contact with a water-based, lubricant-free pressure fluid. The motorised head pulley can by this be used without having to pay attention to the risk of pollution from the hydraulic medium. The motorised head pulley is especially appropriate to drive conveyors in food processing production.

An opening in the housing is closed by a dialysis membrane. A channel defining body cooperates with the membrane to define a flow channel. The unit includes a carrier fluid reservoir and a carrier pump for generating a flow of carrier fluid through the flow channel. By dialysis via the membrane, the flow of carrier fluid is transformed into a flow of sample fluid. A detecting device is coupled to detect an analyte in the sample fluid and for generating a corresponding detection signal. Effluent sample fluid is received in a waste reservoir. Average volume flow during operation is less than 100 mu l/min, allowing for at least 30 days of uninterrupted operation.
