Abstract: A control valve having a rotor for communicating outlet port or ports selectively to fluid drain port or to inlet port so as to change flow direction of fluid to be supplied to fluid operated apparatus. The control valve comprises first and second pistons inserted in a hollow space of the rotor and a compression spring arranged between the pistons. At the operation position(s) of the rotor or the valve, the first piston which is biased by the compression spring oscillatingly blocks and reopens fluid passage formed within the rotor outside the first piston for communicating the inlet port to the outlet port(s) under the influence of the compression spring and fluid pressure of the outlet port(s) from which fluid is constantly drained with a small rate through the valve. Fluid pressure of the outlet port may be varied by varying the force of the compression spring by an advance of the second piston. Consequently, by controlling the advance of the second piston, fluid pressure of the outlet port(s), namely fluid pressure applied to the fluid operated apparatus may be controlled. The control valve thus functions not only as a change-over valve but as a valve for controlling fluid pressure applied to fluid operated apparatus.

Abstract: Filter elements are described in which a pleated cylindrical sheet of non-woven microporous glass fibre filter material impregnated with a binder, which may be silicone, polyurethane, phenolic resin or epoxy resin, is mounted in contact with a cylindrical supporting sheet of, for example, expanded metal for maintaining the filter material against shock pressure loads.  To protect the filter material during assembly a porous layer of protective material may be interposed between the filter material and the supporting cylinder.  The supporting cylinder may be a simple cylinder or pleated so as to fit the filter material.  An activated carbon layer for removing odours during air filtration may be added to the filter material. When the air contains oil mist, a layer containing dye that will be taken up by the oil and discolour the filter element as a warning indication that the filter has become saturated, may be interposed between the filter material and the activated carbon layer.  The filter material may comprise an organic binder holding together borosilicate glass fibres, this amorphous mass being further impregnated by a synthetic resin binder.  The filter material may consist of a glass fibre filter paper with a further layer of non-woven material secured thereto by a synthetic resin binder.

Abstract: The invention relates to a valve assembly for a refrigeration plant of the kind used for controlling the flow of refrigerant from the evaporator to the compressor. The closure member for the valve unit is controlled directly or indirectly by a movable wall of an expansible chamber filled with a refrigerant medium having vapor and liquid phases. The pressure exerted by the vapor phase of the medium provides a bias in a valve opening direction which is directly related to the temperature of the liquid phase and is opposed by a spring bias in the valve closing direction. A heat transfer element such as a heating resistor in the liquid phase is heated or allowed to cool in a controlled manner by an external control unit. A temperature responsive sensor element in the liquid phase of the medium is part of a feedback system for the control unit which allows a selected temperature to be maintained in the chamber which results in a desired constant pressure in a valve opening direction to be maintained in a chamber. A control unit has an evaporator parameter input branch and a second input branch for the feedback temperature sensing element. The control unit has an output for heating the heating resistor in the expansible chamber and a summating section for varying the relative effects of the input branches on the output.

Abstract: The invention concerns a compartment of the type which is part of a lumber sorting mill, for example, and which contains at least two flexible support elements forming the bottom and sides of the compartment in the form of bands, for example, and which can be unrolled and rolled up, and which can be detached at one end to enable emptying of the compartment. In order to reconstitute this type of compartment, the entire band length has to be rolled up before the free ends of the bands can again be fastened to form the compartment, and therefore it takes a relatively long time to reconstitute such compartments. In order to reduce the time of reconstituting the compartment, the invention proposes the arrangement of a boom 25 which is moveable after the releasing of the band ends from the fastening mechanism 17 in order to transfer the bands 10 hanging down from the band drums 11 to the fastening mechanism, before the ends of the bands are permanently engaged with the fastening mechanism 17 by rolling up the band on the drums 11. <IMAGE>

Abstract: a fuel system for mixture-compressing internal combustion engines controls the pressure differential of the extraction air required for proportioning the fuel. The system includes a fuel proportioning device and a vane pump for generating a carrier air stream for transporting the fuel into the suction tube of the internal combustion engine. A control valve constructed as a differential pressure valve influences the air pressure at the fuel outlet area and consequently the differential pressure for fuel proportioning. The throttle point is located in the carrier air channel upstream from the fuel proportioning area. A change in differential pressure adapts the mixture composition for various operating conditions. The signal level of the differential pressure is determined by the pressure decrease at the air quantity measuring valve formed as a pivotal flap and reaches the air channel where it is superimposed by the negative pressure, generated by the vane pump, and can be stabilized by the differential pressure valve and can be varied in dependence on motor operating parameters. To generate adequately high signal levels in the higher load range, the carrier air channels open into a Venturi arranged upstream from the main throttle valve. During different operating phases of the engine, various devices make it possible to maintain an adequately high signal value of the differential pressure.

Abstract: A brake valve for dual circuit pneumatic brake systems is proposed for motor vehicles which have two independent, separately controlled brake systems. A primary piston (18) and a secondary piston (24), which serve for controlling the brake pressure, and associated inlet and outlet valves for the compressed air are arranged in tandem in the operating direction in the valve housing (10). The primary piston (18) is mechanically actuable by way of a final control element (46). The secondary piston (24) is actuated by the pressure in the first brake circuit (20) or by the primary piston (18). Whilst the primary piston (18) is displaceable against the force of at least one return spring (42), the secondary piston (24) is freely movable in the same direction and unloaded by spring reaction forces. It is coupled by means of a coupling element (52) so that it moves together with the primary piston (18) in the opposite direction thereto. If the primary piston (18) closes the venting outlet and opens the compressed air inlet, this occurs practically without any lag even in the case of the secondary piston (24) and the second brake circuit. If the primary piston (18) opens the outlet, the secondary piston (24) is also drawn along by this and opens its outlet without any residual pressure remaining in the second brake circuit (Fig. 1).
