    • A compressor includes a screw rotor and a gate rotor arranged to form a compression chamber. The screw rotor has an outer circumferential surface with at least one groove portion. The gate rotor has a plurality of tooth portions. Preferably, a first plane contains the screw rotor center axis, a second plane orthogonally intersects the screw rotor center axis, and a third plane orthogonally intersects the first plane and the second plane. The gate rotor center axis passes through an intersection point of the first, second and third planes. The gate rotor center axis is inclined relative to the second plane toward the same side as the groove portions of the screw rotor, as viewed in a direction perpendicular to the third plane.
    • 压缩机包括螺杆转子和布置成形成压缩室的浇口转子。 螺杆转子具有至少一个槽部的外周面。 门转子具有多个齿部。 优选地,第一平面包含螺杆转子中心轴线,第二平面与螺杆转子中心轴线正交相交,第三平面与第一平面和第二平面垂直相交。 门转子中心轴穿过第一,第二和第三平面的交点。 当从与第三平面垂直的方向观察时,门转子中心轴相对于第二平面倾斜于与螺杆转子的槽部相同的一侧。

    • A compressor includes a screw rotor and a gate rotor. The screw rotor has a plurality of spirally extending groove portions disposed radially outwardly from the center axis of the screw rotor. The gate rotor has a plurality of tooth portions circumferentially arranged on an outer circumference to engage the groove portions. Preferably, an inclination angle of a groove portion side face contacting the tooth portions is inclined relative to a circumferential direction of the gate rotor varies. Alternatively a first plane contains the screw rotor center axis, a second plane orthogonally intersects the screw rotor center axis, a third plane orthogonally intersects the first and second planes, the gate rotor center axis is on the third plane, and the tooth portions do not overlap the first plane as viewed orthogonally relative to the third plane.
    • 压缩机包括螺杆转子和闸转子。 螺杆转子具有从螺杆转子的中心轴线径向向外设置的多个螺旋状延伸的槽部。 门转子具有周向布置在外周上的多个齿部,以与槽部接合。 优选地,与齿部接触的槽部侧面的倾斜角度相对于门转子的周向倾斜变化。 或者,第一平面包含螺杆转子中心轴,第二平面与螺杆转子中心轴正交,第三平面与第一和第二平面垂直相交,门转子中心轴在第三平面上,齿部不 与第三平面垂直相交的第一平面重叠。

    • A single-screw compressor includes a screw rotor including a spiral groove, a casing, and a gate rotor. The gate rotor includes a plurality of radial gates configured to mesh with the spiral groove. A clearance between one of the gates disposed in the spiral groove and a wall surface of a discharge side portion of the spiral groove is larger than a clearance between the gate disposed in the spiral groove and a wall surface of a suction side portion of the spiral groove. The wall surface of the discharge side portion of the spiral groove is a portion extending from a predetermined position of the spiral groove at a certain point in a compression phase to the terminal end of the spiral groove. The wall surface of the suction side portion of the spiral groove being a portion other than the discharge side portion.
    • 单螺杆压缩机包括螺旋转子,其包括螺旋槽,壳体和闸转子。 门转子包括构造成与螺旋槽啮合的多个径向门。 布置在螺旋槽中的一个门和螺旋槽的排放侧部分的壁面之间的间隙大于设置在螺旋槽中的门与螺旋形的吸入侧部分的壁面之间的间隙 槽。 螺旋槽的排出侧部的壁面是从螺旋槽的规定位置在压缩阶段的某一点向螺旋槽的末端延伸的部分。 螺旋槽的吸入侧部的壁面是排出侧部以外的部分。
