In a freezing cycle, if the pressure in a high-pressure line (8) reaches an abnormal level, the high-side pressure is released toward a low-pressure line (9) to lower the pressure without releasing the coolant into the atmosphere and the coolant is released into the atmosphere only when the pressure in the low-pressure line (9) reaches an abnormal level. A first means for a safety (10) that communicates between the high-pressure line (8) and the low-pressure line (9) is provided and a second mea...

A cycle seat providing rider comfort and accommodating various styles of riding while providing substantially minimal pressure on the urogenital area of the rider during pedalling. The lateral portions of the seat do not interfere with the thighs of the rider during pedalling, thus allowing the legs of the rider to be angle downward to meet the pedals of the seat with substantially minimal obstruction. The cycle seat includes a ridge-like member intermediate to support surfaces which are adapted...

A bicycle (32) includes a seat (20) having a support stem (22), a roller bearing support member (24), a flexible support arm (26), a pair of pivot joints (28), and a pair of seat members (30). The pivot joints (28) comprise ball and socket joints which allow the seat members to pivot about respective sets of axes (X',Y',Z' or X",Y",Z"). Further pivoting motion is provided by the roller bearing support member (24), flexible support arm (26), and by allowing the support arm (26) to pivot. The pivo...

A refrigerating apparatus comprising a refrigeration cycle comprising at least a compressor, a condenser, a dryer, an expansion mechanism and an evaporator, a refrigerant composed mainly of a fluorocarbon type refrigerant containing no chlorine and having a critical temperature of 40.degree. C. or higher, and a refrigerating machine oil comprising as base oil an ester oil of one or more fatty acids which contains at least two ester linkages ##STR1## in the molecule and has a viscosity at 40.degr...

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...

In a freezing cycle that utilizes a supercritical fluid as its coolant and employs an internal heat exchanger that performs heat exchange on the coolant on the outlet side of a gas cooler and on the intake side of a compressor, a means for adjustment that adjusts the quantity of heat exchange performed by the internal heat exchanger (4) is provided. The means for adjustment is constituted of a bypass passage (9) that bypasses the internal heat exchanger (4) and a flow-regulating valve (10) that ...

The freezing cycle according to the present invention is provided with a first means for safety that leaks the high pressure to the low-pressure side when the high pressure reaches a level equal to or higher than a first specific pressure, a second means for safety that releases the high pressure into the atmosphere when the high pressure reaches a level equal to or higher than a second specific pressure, a third means for safety that stops the operation of the compressor when the high pressure ...

A cycle carrier that includes a gripping device (6) which engages with and fixedly retains a portion of a cycle. Further, the cycle carrier includes an operating device (7) with which the gripping device (6) is maneuvered between its closed and its open position. The gripping device (6) is openable against a spring pretensioning which, when it is released, transfers the gripping device (6) to an abutment position against the cycle. The abutment position is determined by the thickness of the fixe...
