    Abstract: A hydraulic control valve for controlling flow between a pump, a hydraulic device, and a vessel containing hydraulic fluid. The control valve has an elongated valve slide which is slidably mounted in an elongated valve housing. The valve has three positions, a central neutral position, a float position axially offset in one direction from the neutral position and a constant pressure position axially offset in the opposite direction from the neutral position. In the neutral position, flow of hydraulic fluid to the hydraulic device is inhibited. In the float position, connection is such that a raised device, such as a hydraulically operated bucket, is lowered slowly by gravity until it rests on the ground or another object. In the constant pressure position, the valve connects pump pressure to the load sensing circuit to facilitate, for example, shaking of a bucket of a piece of earth moving equipment.

    Abstract: The invention concerns a corrosion proof pump or motor with an inner, outside toothed tooth wheel rotating around a first centre, whereby the inner tooth wheel engages an outer, inside toothed tooth wheel rotating around a second centre which is displaced in relation to the first centre, whereby both the inner and the outer tooth wheels rotate between side plates, and the outer tooth wheel rotates in an outer bearing which is at the same time a distance piece between the side plates. The pump or motor is especially suited for media with a low viscosity, in that the side plates and/or the outer bearing and/or at least one of the tooth wheels consist of a binding material containing reinforcement and/or wear resistance improving and/or friction reducing materials.

    Abstract: A micro-mixer (8) is disclosed having at least one mixing point (9, 10) which is connected to an inlet channel arrangement having at least two inlet channels (3, 4) and to an outlet channel arrangement, and a mixing method is disclosed for at least two fluids which are supplied from different directions. With this mixer and method it is intended to achieve a rapid and predeterminable mixing of the fluids. For that purpose, a separating element (5) which extends into a region of the mixing point in which the inlet channels run parallel to one another is provided. By this means the fluids can be kept separate from one another until their flow speeds virtually coincide in respect of value and direction. Only then are they brought into contact with one another.

    Abstract: A control apparatus for a hydrostatic auxiliary power steering arrangement, in particular for vehicles, has a metering motor (10) and two coaxial rotary slide valves (16, 17) forming between them a directional valve (14). The directional valve (14) is opened by rotating the inner rotary slide valve (17) by means of a steering element (57), so that fluid under pressure is allowed to pass through the metering motor (10) to a steering motor (8) and the metering motor (10) adjusts the outer rotary slide valve (16) in dependence on the amount of fluid flowing through the inner rotary slide valve (17). To avoid abrupt changes in the rotational speed of the inner rotary slide valve, and therefore to prevent acceleration forces that are too high being exerted on the steered item and possibly on the person controlling the steering, the inner rotary slide valve (17) is connected to a damping arrangement (70) counteracting its rotational movement.

    Abstract: A unity power factor power supply for an electric motor. A switch-mode circuit is employed which, in a first mode, transfers power from AC main to a constant voltage DC bus. In a second mode, power generated on the DC bus is fed back to the main power supply. The circuit of the invention automatically maintains the DC bus voltage constant and sets an adequate operation mode by processing the DC bus voltage signal. In both operation modes, the unity power factor and sinusoidal waveform of the AC main side are maintained.
