    • An improved axial sealing apparatus for a scroll type apparatus which is capable of constantly maintaining pressure in a back pressure chamber by forming a back pressure hole at a predetermined portion in which the back pressure hole is opened before a compressed gas is discharged and the back pressure hole is closed after the compressed gas is substantially closed, whereby a more stable axial direction sealing can be obtained throughout the entire operation time of a scroll compressor, which includes a stationary scroll; a rotational scroll engaged at a lower portion of the stationary scroll so as to form a compression chamber therebetween; and a back pressure chamber having a back pressure hole formed at a predetermined position in which the back pressure hole is opened whereby the compression chamber and the back pressure chamber become communicated with each other before a refrigerant gas compressed in the compression chamber is discharged to the discharging chamber and in which the back pressure hole is closed after the refrigerant gas is discharged to the discharging chamber, whereby an intermediate pressure having a greater pressure than the suction gas pressure and having a lower pressure than the discharging gas pressure is introduced into the back pressure chamber.

    • A regenerator includes a casing including a connection channel for making a high temperature part and a cooling part communicate with each other; and a thermal energy storage material inserted in the connection channel of the casing and made of an aramid fiber which stores/radiates heat of a working fluid flowing through the connection channel. A cryocooler includes the regenerator. Accordingly, regeneration performance of storing heat included in the working fluid and transmitting the stored heat to a working fluid is improved, and simultaneously a weight is decreased, thereby minimizing abrasion of components.
    • 再生器包括:壳体,其包括用于使高温部件和冷却部件相互连通的连接通道; 以及插入在壳体的连接通道中并由芳族聚酰胺纤维制成的热能储存材料,其存储/辐射流过连接通道的工作流体的热量。 一个低温冷却器包括再生器。 因此,提高了包含在工作流体中并将储存的热量传递到工作流体的再生性能,并且同时减轻了重量,从而使部件的磨损最小化。
