181	IMPROVED INLET PORT CONFIGURATION FOR ROOTS-TYPE SUPERCHARGER	CA3071619	2018-07-27	CA3071619A1	2019-02-07	PETERSON OWEN; THOMAS JONATHAN
A supercharger having twisted meshing rotors sealingly contained within a housing having an inlet port to admit air into the meshing rotors and an outlet port to expel air from the meshing rotors, the rotors having mesh points where the rotors contact one another and spaces between their mesh points to accept air from the inlet port and propel it to the outlet port as the rotors are rotated and the mesh points travel axially, the housing, inlet and rotors defining an angle known as the seal transfer angle which is greater than or equal to zero degrees when the inlet port is closed and the volume of air between rotors is sealed and has no leakage path. In the described supercharger the housing, rotors and inlet port are configured to have a negative seal transfer angle of, e.g., -10 to -40 degrees or more, up to the maximum available, and to provide a leakage path for an angular portion of the rotors' rotation, improving high end performance without degrading low end performance

DISCLOSED IS A GAS COMPRESSOR CAPABLE OF PREVENTING GENERATION OF NOISE DUE TO THE VIBRATION DURING THE ROTATION OF THE ROTOR (250). A ROTOR ROTATING IN A CYLINDER (40) AROUND A ROTATION SHAFT HAS FIVE RADIALLY EXTENDING VANE GROOVES (55), EACH OF WHICH SUPPORTS A VANE. THE RESPECTIVE DIRECTIONS OF THE VANE GROOVES (55) ARE DETERMINED SUCH THAT THE RESPECTIVE ANGULAR DIFFERENCES BETWEEN AT LEAST THREE ADJACENT COMPRESSION CHAMBERS (48) ARE NOT LESS THAN 5 DEGREES. THUS, THE ANGULAR INTERVALS IN TERMS OF DIRECTION BETWEEN THE VANES (55) SUPPORTED BY THE VANE GROOVES (55) ARE ALSO DIFFERENT FROM EACH OTHER. AS A RESULT, THE TIMING WITH WHICH THE VANES PASS THE OUTLET PORT IS IRREGULAR, AND THE DISCHARGE PERIOD IS THUS UNEQUAL BETWEEN A PLURALITY OF COMPRESSION CHAMBER (48), WHEREBY THE PERIODICITY OF THE VIBRATION BASED THEREON IS REDUCED, AND THE PEAK VALUES OF THE BASIC VIBRATION COMPONENT ARE REDUCED.(FIG 6)

A disturbance estimated type control system and a gas compressor control system that are insensitive to a parameter variation such as a heat load variation and a rotating speed change and a method of designing a disturbance estimated type control system are provided. A disturbance is applied to a control object. An input signal and an output signal are inputted in an observer and a disturbance is estimated. A deviation between the output signal and a target value is calculated by a subtractor. This deviation is subject to compensations by a compensator and outputted as a control signal. This control signal is subtracted from a disturbance estimated value from the observer by a subtractor. Therefore, the disturbance estimated value among estimated values of the observer is fed back so as to cancel an actual disturbance.

The scroll compressor has a fluid capacity and a compression cycle. A fixed scroll is mounted in a housing and has a central discharge port and a first pair of by=pass ports. The pair of by=pass ports are located at thermodynamically symmetrical points in the compression cycle relative to the discharge port. A moving scroll is mounted in the housing and is intermeshed with the fixed scroll to trap a fluid between the fixed and moving scrolls. A rotatable, hollow, cylindrical control valve has a valve wall with a first pair of slots controllably alignable with the pair of by=pass ports to vent the trapped fluid and modulate the fluid capacity of the scroll compressor. The control valve has first and second end portions of equal diametrical dimension and a middle portion intermediate the first and second end portions of lesser diametrical dimension than the first and second end portions. The middle portion and the fixed scroll form a passageway for fluid exiting the discharge port.
