Abstract: Eine Rotationskolbenmaschine (1) umfasst ein Gehäuse (2), das mehrere Öffnungen (10, 10a, 10b) zum Einlassen und Auslassen eines Arbeitsmediums aufweist und in dem eine Welle (3) drehbar gelagert ist. Die Rotationskolbenmaschine (1) umfasst weiter zwei konzentrisch auf der Welle (3) drehbar angeordnete Rotoren (17) mit jeweils mehreren kreissektorförmigen Flügeln (19). Die Rotoren (17) sind einander gegenüberliegend angeordnet und greifen derart ineinander, dass ein Flügel (19) des einen Rotors (17) zwischen zwei Flügel (19) des anderen Rotors (17) positioniert ist. Zwei Steuerungseinheiten (6) sind jeweils ausgebildet, die Winkelgeschwindigkeit einer der Rotoren (17) derart zu steuern, dass die Flügel (19) beider Rotoren (17) mit sich zyklisch verändernden Winkelgeschwindigkeiten in einem Arbeitsraum (13) in dem Gehäuse (2) rotieren und sich die Abstände zweier aufeinanderfolgender Flügel (19) in Rotationsrichtung (R) der Flügel (19) zyklisch ändern.
Das Gehäuse (2) weist eine hohlzylindrische Laufbuchse (11) auf, die reversibel in eine Aufnahme des Gehäuses (12) eingesetzt ist. Die Laufbuchse (11) begrenzt den Arbeitsraum (13) vollumfänglich und die Flügel (19) liegen an der Laufbuchse (11) dichtend an und sind entlang dieser bewegbar. Die Laufbuchse (11) weist Einlass- und Auslassöffnungen auf. Die Laufbuchse (11) ist in dem Gehäuse (2) derart angeordnet, dass die Einlass- und Auslassöffnungen der Laufbuchse (11) mit den entsprechenden Öffnungen (10, 10a, 10b) in dem Gehäuse (2) verbunden sind.

Abstract: A compressor unit includes a compressor (1) and an accumulator (2) adjacent to the compressor (1). In a frequency range between a frequency having a value three times larger than a maximum rotation speed of the compressor (1) and a frequency 1.25 times greater than the frequency having a value three times larger than the maximum rotation speed of the compressor (1) when a first part is vibrated, an index showing a frequency response function of the second casing (61) in a circumferential direction in a second part is 1.0 m/s2/N or less, where the first part is a part of an upper part of a side surface of the first casing (10) of the compressor (1) and is orthogonal to an alignment direction of the compressor (1) and the accumulator (2), and the second part is a part of an upper part of a side surface of the second casing (61) of the accumulator (2) and is opposed to a part facing the first casing (10).

Abstract: An inflow end (51) of a discharge port (50) has a hydraulic diameter Di expressed by Di = 4 × (Ai/Li), where Ai is an area of the inflow end (51) and Li is a circumferential length at the inflow end (51). An outlet flow path (70) is formed between an outflow end (52) of the discharge port (50) and a valve body (61). The outlet flow path (70) has a cross-sectional area Ao expressed by Ao = Lo × ho and a hydraulic diameter Do expressed by Do = 4 × {Ao/(Lo + Lv)}, where Lo is a circumferential length at the outflow end (52) of the discharge port (50), ho is a reference lift amount of the valve body (61), and Lv is a circumferential length of a valve head (64) of the valve body (61). The hydraulic diameter ratio (Do/Di) in this case is 0.602 or more and 0.740 or less.
