In an ejector cycle with an ejector including a nozzle for decompressing refrigerant, a refrigerant outlet is provided in an evaporator at a position upper than a refrigerant inlet. Therefore, a circulation performance of refrigerant flowing in the evaporator can be improved. Accordingly, even when a pumping capacity generated in the ejector becomes smaller, a sufficient amount of refrigerant can be drawn into the ejector from the evaporator. Thus, a refrigerant amount supplied to the evaporator...

A wheeled vehicle that is convertible between a bicycle mode and a scooter mode. The cycle scooter includes a front wheel drive system with an operator seat that is movable between a lowered position that provides for comfortable operation of the vehicle in the bicycle mode, and a raised position for comfortable operation in the scooter mode. The frame includes rear and front portions that are pivotally attached and movable between a folded storage position and an extended operating position.

A refrigeration apparatus is constructed by connecting a sight glass via a refrigerant pipe at a downstream side of a supercooling unit of an integrated type condenser-receiver. A required capacity VR of a receiver is obtained by subtracting a required capacity V3 for making the sight glass bubble-free from a total of a refrigerant fluctuation buffer amount V1 for accounting differences in the operating conditions of the refrigeration cycle, and an extra capacity to account for leakage of refrig...

A trailer cycle (10) includes a trailer cycle frame (52) having a main tube (54) which extends toward the lead cycle (12). A hitch mechanism (14) is located between the lead cycle and the trailer cycle. A lead-cycle hitch portion (34) is joined to the lead cycle substantially vertically above the hub of the lead-cycle rear wheel (26). A flexible hitch portion (82) is interposed between the trailer cycle frame and the lead cycle hitch portion and is housed in an orthogonal member (84) which conta...

A refrigeration cycle that controls the deposit of foreign matter at inlet or outlet of a capillary tube, which forms an expansion device in the refrigeration, regardless of changeover from a cooling operation to a heating operation. In particular, in a refrigeration cycle using an alternative refrigerant, a junction is provided for joining an end of a capillary tube forming an expansion device to the piping through which the refrigerant flows. The junction has a slope defined by the inside diam...

A children's cycle comprising frames, wheels under the frames and a push-handle connected with the frames. The push-handle is arcuate in shape and movably connected with the frames. The push-handle may be turned down to the underside of the cycle body with its arcuate concave facing upward so that the cycle body is supported by the push-handle. The push-handle may be used for pushing or pulling the cycle, and may be turned down to the underside of the cycle body for rocking the cycle forward and...

A refrigerating cycle is capable of performing both an operation in which the maximum cooling power is desired to be unleashed and an operation in which the most excellent performance coefficient is attained. A refrigerating cycle is configured such that a differential pressure-regulating valve forming a pressure-reducing device is arranged between a condenser and a receiver. As a result, by setting the differential pressure regulated by the differential pressure-regulating valve 3 to 0, it is p...

A highly reliable refrigeration cycle having a residual refrigerant, which is designed that the refrigerating machine oil does not stagnate in the refrigeration cycle after flowing out from the compressor even if the refrigerating machine oil is weakly soluble in a refrigerant. Thus, the compressor may be prevented from the exhaustion of oil. In addition to that, even if the accumulator is removed from the cycle, a large amount of wet vapor suction into the compressor may also be avoided. A cont...

A cycle seat such as a bicycle seat which comprises an abutment section which is inclined with respect to the horizontal. The abutment section is formed from two abutment segments which are connected together. The segments are dimensioned to support the gluteus maximus muscles adjacent the ischial bones so that the majority of the gluteus maximus muscles are not in contact with the seat and wherein the segments do not allow the rider to permanently sit in a vertical position without other suppor...
