SPIRAL MACHINE Russian patent published in 2009 - IPC F04C29/04 F04C2/04 F04C18/04 

FIELD: motors and pumps.

SUBSTANCE: invention relates to pump and compressor engineering and may be used in spiral machines to solve the problems of thermal loads reduction from the structural elements and improve output performance. The spiral machine consists of a housing with openings for gas intake and injection and fixed spiral element provided with the basis and spiral rib and geared with the movable spiral element also provided with the basis and spiral rib. The movable spiral element is mounted on the eccentric shaft so that it can move eccentrically regarding the fixed element creating the closed compression space between spiral ribs. The spiral machine also includes rotation-preventing device and cooling medium supply facility. The fixed spiral element is provided with the second spiral rib from the other side of the basis. Together with the above side surfaces and housing, it forms the channel for cooling medium movement. The second rib and cooling medium channel are implemented in the helical form. The second rib repeats the shape of spiral rib located on the opposite side. So, the cooling medium moves along helical channel from the centre to channel periphery.

EFFECT: provision of improving spiral machine elements cooling, reliability and service time.
