Abstract: A swirling compressor comprises a number of swirling tubes and a motor, each swirling tube has a fixture at a center portion with a flange bulging out from one side and a hole at the other end of the center portion opposing the flange, an aperture is formed close to the center end at the inside of the tube, this fixture design allows the swirling tube to pile up with one over the other forming a wind passage, and a spindle of a motor is inserted through the hole and secured thereat. When the motor driven the swirling tubes set to spin, each tube collects a portion of whirlwind, and all whirlwind will be blown out from the fixture.

Abstract: A rotary valve includes a valve seat containing a circular valve block comprising two abutted semicircular blocks and a space inside the valve seat; an axial plunger each at the centers of the upper and the lower sides of the semicircular blocks; an air inlet and outlet passage each formed within each semicircular block extending from periphery to the axial plunger; a trough in the periphery of each semicircular block; and a hole connecting the periphery of the valve seat and its interior; power from a linkage mechanism being introduced to drive the circular valve block to rotate so that a specific timing being given to air circulation through the passages and the hole during the travel, of rotation executed by the two semicircular blocks to change connection configuration of the passages to control air inlet and exhaustion.
