摘要： A scroll compressor has a fixed scroll and an orbiting scroll nested with one another within a shell. A hub extends axially from a lower surface of the orbiting scroll with a central bore formed therein. A crankshaft, having an eccentric pin extending axially from one end thereof, is drivable by a motor. A passageway for the delivery of a lubricant extends through the crankshaft and the eccentric pin. A slider block is received by the central bore, and a pin bore, which extends axially through the slider block, receives the eccentric pin. An axially extending projection maintains a gap between the slider block and the orbiting scroll which enhances the flow of lubricant to bearing surfaces of the scroll compressor.

摘要： An improved Oldham coupling ring is relatively easy to manufacture. Opposed circular arc portions are connected by angled portions to opposed flat portions. The circular arc portions are centered on a common center. As such, the invention is relatively easy to manufacture when compared to prior art systems.

摘要： An improved slider block for a scroll compressor has a bore including two spaced circular portions centered on a common axis. A recess is formed into one of the curved portions to provide additional clearance for movement of an eccentric pin. The recess allows the eccentric pin to move within the bore, as the relative position of the slider block and the eccentric pin move and change during operation of the scroll compressor.

摘要： An improved check valve for a scroll compressor has a stop body which has a contact face which is reduced in surface area to reduce the stiction or holding force holding the valve at shut down. In this way, the valve is allowed to move to its closed position more rapidly.

摘要： An oil spout is drilled in the crankcase of a scroll compressor between the outer seal and the coupling. The oil spout intersects the oil return chamber to redirect a portion of the oil exiting the oil return passage to the lower surface of the orbiting scroll between the outer seal and the coupling. It is preferred that the oil spout be substantially perpendicular to and smaller in diameter than the oil return passage. The oil spout provides a continual flow of additional lubrication to the outer seal and the coupling, preventing excessive wear of the outer seal and improving overall seal reliability.
摘要翻译： 在外密封件和联接器之间的涡旋压缩机的曲轴箱中钻出一个喷油嘴。 油嘴与回油室相交，以将从油回流通道出来的油的一部分重新定向到外密封件和联接器之间的绕动涡盘的下表面。 优选的是，喷油嘴基本上垂直于直径并且小于回油通道的直径。 喷油嘴为外部密封和联轴器提供持续的附加润滑，防止外部密封件过度磨损并提高整体密封可靠性。

摘要： A method of forming a drive surface on an eccentric pin of a drive shaft for a scroll-type compressor is provided. First, an eccentric pin having an axis and a generally cylindrical outer surface disposed radially about the axis is provided. Next, a broaching tool having a machining face with a contour is provided. The contour may be a concave shallow bell-shaped curve. Finally, the drive surface is formed by engaging the outer surface with the machining face transverse to the axis. In this manner, the machining face forms a shape complementary to the contour on the eccentric pin thereby forming a slight crown on the drive surface. The broaching tool produces an adequate surface finish so that no subsequent machining operations to the drive surface are necessary.
摘要翻译： 提供了一种在涡旋式压缩机的驱动轴的偏心销上形成驱动面的方法。 首先，提供了具有轴线和径向地布置在轴线周围的大致圆柱形的外表面的偏心销。 接下来，提供具有轮廓的加工面的拉刀。 轮廓可以是凹形的浅钟形曲线。 最后，通过使外表面与横向于轴线的加工面接合而形成驱动表面。 以这种方式，加工面形成与偏心销上的轮廓互补的形状，从而在驱动表面上形成微小的凸起。 拉削工具产生足够的表面光洁度，使得不需要对驱动表面的后续加工操作。

摘要： An improved slider block for a scroll compressor has a bore including two spaced circular portions centered on a common axis. A recess is formed into one of the curved portions to provide additional clearance for movement of an eccentric pin. The recess allows the eccentric pin to move within the bore, as the relative position of the slider block and the eccentric pin move and change during operation of the scroll compressor. In a further embodiment, chamfers are formed at circumferential ends of a non-drive flat surface to merge that non-drive flat surface into the circular portions. This will ensure the slider block is properly positioned on smaller eccentric pins.
