Abstract: The expansion valve (8) of refrigeration appts. heat pump is controlled by an electric motor (4) which adjusts the opening of the valve in accordance with a control signal derived from the outputs of a pair of temp. sensors (5,6) connected to the inlet and outlet ports of the evaporator (3). causing the coolant to flow at a suitable rate as determined by a microprocessor. If the temp. at the inlet of the evaporator lies above a first predetermined valve, the expansion valve is set to a predetermined value, otherwise the valve opening is proportional to the difference between the inlet and outlet temperatures of the evaporator. The expansion valve may be fully closed whenthe inlet temperature exceeds a second predetermined value. A-d converters may convert the analogue sensor outputs into digital form suitable for the microcomputer. The motor may be a 2-phase bipolar stepping motor.

Abstract: A single or oppposite direction damper hinge has a casing (10) rotatably enclosing a rotor (30). The rotor (30) has a center cylindrical portion (36) mounting a reduced outwardly projecting intermediate portion (38) which in turn outwardly mounts a further reduced stop portion (44). The casing (10) has a main inner cylindrical surface (16) which is interrupted by an inwardly projecting reduced engagement portion (24). In one embodiment, all of the rotor center, intermediate and stop portions (36,38, 44) and the casing main inner surface (16) are coaxial. The casing reduced engagement portion (24), however, has a larger radius than the outwardly projecting intermediate portion (38) of the rotor (30) and is eccentric to the rotor outer surfaces and the casing main inner cylindrical surface (16). In assembly for operation, the rotor (30) is mounted coaxially in the casing (10) with the exception of the casing engagement portion (24) which, in this embodiment, has the larger radius and is eccentric to the rotor intermediate portion (38). The rotor intermediate portion (38) radially faces the casing engagement portion (24) with the surfaces progressively closing due to the casing engagement portion (24) larger radius and eccentricity, and the rotor stop portion (44) interfering with the casing engagement portion (24) ultimately abutting through facing steps (26,46).
