摘要:
A heat exchange tube (4) is constituted of sheet members not covered with a brazing material layer, and a joint width (4d) where the sheet members are overlapped is brazed with a brazing material. The structure above reduces the possibility of spreading of the brazing material while the heat exchanger tube is being brazed and of dissolution of the tube by erosion. As a result, tube quality, such as corrosion resistance, is prevented from being affected by thinning of a tube material.

摘要:
A compressor capable of damping the suction pulsation or discharge pulsation thereof with a simple structure, wherein either of a suction chamber and a discharge chamber formed at the center of a rear head is allowed to communicate with a corresponding port through a tunnel-shaped communication path and a muffler space is formed between the tunnel-shaped communication path and a pipe connection part for connecting the port thereto, whereby, when the communication path allows the suction chamber to communicate with the pipe connection part of the suction port, the suction pulsation can be suppressed or prevented and, when the communication path allows the discharge chamber to communicate with the pipe connection part of the discharge port, the discharge pulsation can be prevented.
摘要:
A variable displacement swash plate type compressor, comprising a thrust flange (40) fixed to a shaft (5) and rotated integrally with the shaft (5), a swash plate (10) connected to the thrust flange (40) through a link mechanism (42) and rotated integrally with the thrust flange according to the rotation of the thrust flange (40), a hinge ball (9) installed slidably on the shaft (5) and restricting the angle of the swash plate (10) relative to the shaft (5), and pistons (7) connected to the swash plate (10) through shoes (11) rotated on the sliding surfaces (10a, 10b) of the swash plate (10) relative to each other and performing a linear reciprocating motion in the cylinder bores (6) according to the rotation of the swash plate (10), wherein the inclination angle of the swash plate (10) varies according to a pressure variation in a crank chamber (8) for storing the swash plate (10) so as to vary the amount of stroke of the pistons (7), and the center (O1) of the hinge ball (9) is positioned on the front side of the center (O2) of the plate part (10c) of the swash plate (10).
摘要:
A refrigerating cycle, wherein supercritical fluid is used as refrigerant and an internal heat exchanger is installed for heat-exchanging refrigerant between the outlet side of a gas cooler and the inlet side of a compressor, having a regulating means which regulates the amount of heat exchange of the internal heat exchanger (4) and comprises a bypass passage (9) to bypass the internal heat exchanger (4) and a flow control valve (10) to control the flow rate of refrigerant through the bypass passage (9). The flow control valve (10) uses a solenoid valve which determines the opening based on the information on cycle conditions and a bellows type control valve which responds to a pressure on the high pressure side, and the regulating means may change the length of the passage used for heat exchange in the internal heat exchanger (4). A cycle balance is controlled to maintain an optimum high pressure and attain a satisfactory cycle efficiency. The refrigerating cycle can be protected temporarily against the excessive rise of high pressure and delivery side temperature of a compressor.
