    摘要: A lubrication path to press-contact surfaces of a fixed and orbiting scrolls serves also as a high-level pressure introduction passageway when a difference between a high-level pressure and a low-level pressure is great. On the other hand, when the high-level pressure introduction passageway is blocked off in a state in which the high-low pressure difference is small, refrigerating machine oil is supplied to the press-contact surfaces through a low-level pressure space within the casing, for controlling the pressing force of the orbiting scroll against the fixed scroll, and the construction for preventing a decrease in efficiency is simplified, thereby not only reducing the cost but also preventing the occurrence of a maloperation.

    摘要: A rotary fluid machinery includes a fixed member, a drive shaft driven and rotated about a rotation axis, a movable member, a movable member support part and a reverse moment generating mechanism. The movable member is rotatably mounted at the drive shaft with its center being eccentrically disposed relative to the rotation axis, with the movable member and the fixed member forming a fluid chamber. Revolution of the movable member changes the volume of the fluid chamber. The movable member is configured to swing in association with its revolution. The reverse moment generating mechanism generates a moment in a reverse direction about the rotation axis relative to a moment about the rotation axis caused by the revolving movement of the movable member.
