Abstract:
The compressor (1) for the transport of gases is fitted with a vane wheel (2) enclosed in a cover (4). The cover (4) is equipped with at least one entry duct (5) and at least one exhaust duct (6). The bases (7) of the vane wheel (2) are not axially aligned and their axes (o) of rotation are parallel. The vanes (3) are arranged between the bases (7) and are tiltable to be able to adapt to the non-axial alignment of the bases (7) of the vane wheel (2). In addition, the compressor (1) is fitted with at least two compression barriers (8, 9) arranged on the opposite sides with regard to the outer and inner rims of the vanes (3) to form the compression space between at least two consecutive vanes (3), and the inlet of the exhaust duct (6) is fitted with the separator (10).
Abstract:
A rotary compressor that may include an upper or outboard bearing above the motor components and, in this case, includes an upper bearing plate having a structure that ensures bearing alignment when press fit with an upper cap and a center shell. In some implementations, a main bearing frame that secures and holds a main bearing has a structure that when press fit with a lower cap and center shell ensure bearing alignment. Some implementations include disposing a hermetic terminal and a discharge port a the side of the upper cap or center shell.
Abstract:
A supercharged internal combustion engine (10) has a supercharger (11) operable to selectively supply a mass of air from below through above atmospheric air pressure according to the operating requirements of the engine (10). The supercharger (11) has a shuttle (87) combined with a throttle valve (46) that controls the mass of air directed to an air mass bypass opening (84) and supplied to the internal combustion engine (10). The shuttle (87) has rollers (124,126,131,132,133,134,136,137) that ride on rails (143,148) that allow the shuttle (87) to move to open and close the air mass bypass opening (84) in communication with a casing (41) that directs a mass of atmospheric air and a bypass mass of air interfused with the mass of atmospheric air to an air mass inlet (50) of the supercharger (11).

Abstract:
The present invention deals relates to vane pump with variable discharge volume, comprising: a pump housing; a cam ring having an elliptical cross-section for its inner circumference and outer circumference to form a compression chamber wherein a compression medium is compressed, and is accommodated in said pump housing so that it may rotate; a rotor that is accommodated such that a plurality of vanes may appear frequently on the outer circumference to undergo rotations in the compression chamber of said cam ring and compress said compression medium; and a cam ring rotation controller that contacts the outer circumference of said cam ring, and rotates said cam ring if the discharge pressure of said compression medium is equal to or more than its pressure setting and stops the rotation of said cam ring if the discharge pressure of said compression medium is less than its pressure setting to control rotations of said cam ring. Accordingly, the rotation and stoppage of rotation of the cam ring is accomplished based on changes in the discharge pressure, to enable variation in discharge volumes, and enhancement of discharge efficiency.
