Abstract: A compressor may include a shell assembly, a first scroll, a second scroll, a driveshaft, and a bearing. The first scroll includes a first end plate and a first spiral wrap extending from the first end plate. The second scroll includes a second end plate and a second spiral wrap extending from the second end plate. The spiral wraps engage each other to form fluid pockets. The driveshaft may engage one of the scrolls. The bearing supports the driveshaft for rotation relative to the shell assembly. The bearing includes first and second axial ends and an aperture extending through the first and second axial ends. The driveshaft extends through the aperture. The aperture is defined by an inner diametrical surface of the bearing. The inner diametrical surface may include a tapered portion that extends radially outward as the tapered portion extends axially toward the first axial end of the bearing.

Abstract: A compressor may include a scroll member, a hub, a discharge valve and a bypass valve. An end plate of the scroll member includes a recess, a discharge passage in communication with the recess, and a bypass passage in communication with the recess and disposed radially outward relative to the discharge passage. The hub may be received in the recess and may include a central opening in communication with the discharge passage and the bypass passage. The discharge valve may be disposed between the hub and the end plate and may control fluid flow through the discharge passage. The bypass valve may be disposed between the hub and the end plate and may be movable between a first position restricting fluid flow through the bypass passage and a second position allowing fluid to flow through the bypass passage, around the discharge valve and through the central opening.

Abstract translation: 压缩机可以包括涡旋件，轮毂，排放阀和旁通阀。 涡旋构件的端板包括凹部，与凹部连通的排出通道和与凹部连通并且相对于排出通道径向向外设置的旁通通道。 毂可以容纳在凹部中，并且可以包括与排出通道和旁路通道连通的中心开口。 排出阀可以设置在轮毂和端板之间，并且可以控制通过排出通道的流体流动。 旁通阀可以设置在轮毂和端板之间，并且可以在限制流过旁通通道的流体的第一位置与第二位置之间移动，第二位置允许流体流过旁通通道，排出阀周围并通过中心开口 。
