    摘要： The present invention relates to the technological field of compressors and components and/or devices for compressors. Problem to be solved: The current state of the art includes cooling system of dual evaporation and/or dual suction. On the solutions already existing, the selection of one among the two evaporation/suction lines is done by high complexity constructive mechanisms. Problem resolution: The invention in question aims to simplify the construction of a selection mean of one among two evaporation/suction lines. For so, is revealed a suction acoustic filter for reciprocating compressor which integrates an automatic valve coupled to the inlet way of the suction acoustic filter and a valve of a way is coupled to the inlet way of the suction acoustic filter, being said automatic valve and said valve of a way acting selectively reciprocating, where the valve opening of a way ends up opening the automatic valve.

    摘要： A centrifugal dispenser comprises a first container that has a first wall with a lower end defining at least a portion of a first reservoir. The first wall also has an upper end extending above the lower end. A first centrifugal chamber that is at least partially defined by the upper end of the first wall is fluidly coupled to the first reservoir and located centrifugally downstream of the first reservoir. A second centrifugal chamber is located centrifugally downstream of the first centrifugal chamber. A second container defining a second reservoir is fluidly coupled with the second centrifugal chamber and an orifice is located in the upper end of the first wall and has a valve that fluidly couples the first and second centrifugal chambers.

    摘要： A method for controlling and adjusting the refrigeration capacities of a refrigeration system equipped with a double suction compressor, the refrigeration system including first and second compartments to be refrigerated and including first and second evaporators respectively positioned in the first and second compartments. The double suction compressor is controlled to alternate its compression capacity with high-frequency between first and second refrigerant suction lines respectively associated with the first and second evaporators such that the first and second compartments are simultaneously cooled. The compression capacity of the compressor is applied to the first and second suction lines based upon respective first and second duty cycles that together account for 100 percent of the compression capacity of the compressor. First and second temperature sensors are associated with the first and second compartments and provide temperature values that are used to select the first and second duty cycles.

    摘要： The arrangement of the present invention is applied to a compressor which comprises a bearing hub housing a crankshaft and presenting at least a first and a second bearing portion, spaced apart by a circumferential recess. The crankshaft presents at least a first and a second support portion, spaced apart by a circumferential recess, which is offset from the circumferential recess of the bearing hub. At least one of the bearing portions and support portions has an axial extension superior to that required for radially bearing the crankshaft, the first and second bearing portions defining, with the first and second support portions, respectively, a first and a second radial bearing regions having the axial extensions required for a radial bearing for the crankshaft, presenting lower loss by viscous friction.

    摘要： The linear compressor comprises a shell (10) which affixes a cylinder (20) defining a compression chamber (21) housing a piston (30); a linear electric motor (40) having a fixed part (41) and a reciprocating movable part (42); an actuating means (50) driven by the movable part (42); an elastic means (60a) coupling the actuating means (50) to the piston (30), so that they are reciprocated in phase opposition. A supporting elastic means (70) connects the actuating means (50) to the shell (10) and presents a radial stiffness for supporting the lateral loads actuating on said movable part (42) and actuating means (50), and for minimizing the axial misalignments between the movable part (42) and the fixed part (41) of the linear electric motor (40), the supporting elastic means (70) presenting a minimum axial stiffness for allowing the displacement of both the piston (30) and the actuating means (50).

    摘要： A laundry appliance includes a clutch/coupler floating member positioned between basket and stirrer and provides selective and automatic coupling therebetween according to the phase of the washing cycle. At least one coupler cooperates pivotally and simultaneously with the moving basket and the stirrer. The coupler comprises a stem rotatably hinged to a pivot which cooperates with the basket and is disposed orthogonal to the longitudinal axis of the stirrer, wherein a rod end of the coupler cooperates with at least one first coupling member and the other end of the rod cooperates with at least one floating body. The basket comprises at least one housing cooperating with the floating body of the coupler. The stirrer comprises a coupling cooperating with the first coupling member of the coupler.
