Abstract: The invention concerns a refrigeration system comprising a refrigerant circuit which comprises several evaporator paths and a distributor (5) which distributes the refrigerant on the evaporator paths. The aim of the invention is to improve the operation of said refrigeration system in a simple manner. According to the invention, the distributor (5) comprises a controllable valve (12) for each evaporation path.

Abstract: A valve (4) for a refrigeration system. Comprises two diaphragms (8, 10) being operatively connected. One diaphragm (8) is in contact with the refrigerant, the other (10) is in contact with the filling fluid. The two diaphragms (8, 10) may have different active areas. In combination with the connection between the two diaphragms (8, 10) this provides a ‘pressure gearing’ between the filling fluid and the refrigerant. Allows the pressure of the filling fluid to be relatively low even when the pressure of the refrigerant is high, while ensuring that the valve (4) can function properly. Particularly suitable for high pressure refrigeration systems, such as CO2 systems.

Abstract: An operating device (1) with a top part (2) having an actuating arrangement (5) and a bottom part (3) carrying the top part (2). The top part (2) and bottom part (3) are releasably joined to one another and the actuating arrangement (5) drives a control member (6). In an operating device of this kind it is desirable for the top part (2) to be easily mounted on the bottom part (3) and to be easily detachable therefrom. For that purpose the top part (2) and the bottom part (3) are joined to one another by a bayonet joint (16,18).

Abstract: An electromagnetic valve assembly having upper and lower modules. A standardized lower module can be joined with one of several upper modules having a different axial length for varying the magnetic field strength of a coil arrangement in the upper module without changing the length or position of an armature tube in the lower module.

Abstract: An electromagnetic valve assembly having a valve unit with a valve seat and a coil arrangement. An armature is slidably disposed in the bore of the coil arrangement. A yoke unit surrounding the coil arrangement is in two parts having cooperating longitudinally extending edges forming two axially extending air gaps on diametrically opposite sides of the yoke unit. End flange portions of the two parts of the yoke unit are cut to form articulated tabs which facilitate the forming of the flange end portions.

Abstract: An electromagnetic valve assembly having a valve unit with a valve seat and a coil arrangement. An armature is slidably disposed in the bore of the coil arrangement and has one end cooperable with a core head to form an air gap and at the other end a closure device cooperable with the valve seat. The closure device has a ring shaped mounting part attached to the armature and a closure element in the form of a radially inwardly extending tongue-like part which is resiliently connected to the mounting part and is cooperable with the valve seat to maximize the operating effects of the coil arrangement.

Abstract: The coil arrangement of an electromagnetic valve has a stationary core that is provided with a stop face for having one end of an armature abut thereagainst. The stop face and the one end of the armature is located in a damping chamber, the other end of the armature mounting a closure member for abutting against a valve seat to block fluid flow therethrough. Between the armature and the guide member there is a throttle path that fluidly connects the damping chamber with the valve seat chamber. The electromagnetic valve is especially suitable for conveying contaminated media.

Abstract: The magnetic valve includes a magnetic coil, at least one valve seat, a valve shank surrounded by a valve plate member and movable upon energizing of the coil to move the surrounding valve plate member away from the valve seat to permit fluid flow therethrough, and a resetting spring for resiliently retaining the valve member in a position for blocking fluid flow through the valve seat when the coil is deenergized. The spring action acting upon the valve plate member moves the valve shank away from the coil upon denergization of the coil. The valve plate member is movable relative to the shank and includes an annular resilient metal plate that has radial inwardly extending teeth and a coating of elastic plastic sprayed on to the plate to leave at least part of the teeth uncoated.

Abstract: An electrical conductor clamping apparatus comprising a housing and juxtaposed clamping positions each of which has a clamping member held against rotation in a guide passage. A screw of the clamping member passes through a counterbearing and is held in a receptacle formed by the guide passage and a cover member which defines holes for operating the screwhead. Stiffening of the cover member is obtained in that the cover member is connected to the housing base by way of struts extending perpendicular thereto, allowing the cover member to be comparatively wide without losing its strength. The cover member and the housing are formed in one piece. The clamping members are carried by insert blocks which are received in the clamping positions, securable to the housing by a snap action.

Abstract: The invention relates to a coil assembly and a method for making same. In particular the invention is directed to the attachment of a terminal pin to the coil assembly base plate and the connecting of the terminal pin to an end portion of the coil wire in a manner which lessens the chances of inadvertently breaking the coil wire.

Abstract: The invention relates to an electric snap switch assembly. The assembly includes a two part carrier unit with at least one leaf spring mounted in one of the carrier parts. The other carrier part is spaced from the free end of the leaf spring and a bearing is mounted on the second carrier part in spaced relation to and in the same plane as the leaf spring. An omega spring is mounted between the bearing and the leaf spring, and bearing control means are provided for moving the bearing in any direction in the plane of the leaf spring.

Abstract: The invention relates to a timing pulse generating switch assembly, particularly for the monitoring circuit of an oil or gas furnace, having at least one snap switch provided with a contact arm which carries the movable contact. The movable contact arm is fixed with respect to the housing at one end and there is provided a snap system which adjusts the contact arm. The snap system possesses a snap arm which is fixed with respect to the housing at one end and is preferably formed by the contact arm. The snap system includes a snap spring which is articulated to the snap arm and, at its other end, is articulated to a slide that is reciprocatable by a bimetallic member. The switch assembly includes and is influenced by a locking element that is actuated by separate means such as the armature of a relay. The locking element functions to block the movable contact in its rest position as well as in its operating position by using a blocking member which is carried along by the slide.

Abstract: The invention relates to an electrical type contact switch assembly. The assembly includes an insulated contact carrier having a U-shaped portion with spaced apart walls. A slot for receiving a leaf spring extends transversely through the walls. Mutually facing depressions formed in the walls straddle the slot and have oppositely inclined surfaces. A leaf spring disposed in the slot has a resiliently hinged flap extending at an acute angle relative to the plane of the spring. The flap is in resilient biasing engagement with the inclined surfaces of the contact carrier. The flap is of trapezium shape and is an integral part of the spring.

Abstract: The invention relates to an omega type spring assembly and particularly the pivotal connection between the omega spring element and a bearing element. In a broad sense the invention involves replacing the conventional knife edge pivotal with a ball and socket connection in which the "socket" has the form of an elongated aperture with arcuately shaped edges. The "ball" has a tapered portion which engages the edges and the tapered portion may be spherical, conical or elliptical in shape. There are two contact points between the bearing element and the arcuately shaped edges of the aperture in the omega spring element.
