摘要： An improved geometry for scroll wrap inner portion includes a groove which facilitates opening of the compression chambers to the discharge ports early in the cycle of the orbiting scroll. Stated one way, a forward end of the scroll wrap tip is thinner than a portion spaced from the forward end. A first curve defines the forwardmost end of said tip and extends to a forward ledge. A second circular curve is spaced from the forward ledge and extends to a rear ledge. An intermediate curve connects the forward and rear ledges. The rear curve is centered on a second radius, and if the second radius were extended beyond the rear ledge, the extension would move to a position spaced from the forward ledge and towards the opposed wrap. The swing radius for the scroll compressor wrap measured begins at the position wherein the forward ledge of one wrap faces the rear ledge of an opposed wrap begins on one side of zero, then crosses zero with an increasing scroll wrap, and then moves to an opposed side of zero. The inventive scroll compressor wrap achieves more rapid and smooth opening of the compression chambers to the discharge ports.

摘要： A scroll compressor has an economizer injection line communicating into the scroll compressor chambers. An unloader valve selectively communicates the economizer injection line back to suction. In this arrangement, the fluid ports and passages necessary to achieve the economizer injection are also utilized to achieve suction bypass unloading, and thus the compressor and system design and construction are simplified.

摘要： An improved control over the pressure vented or tapped to a back pressure chamber in a scroll compressor is achieved by maintaining a vent hole closed for the majority of the operational cycle of the scroll compressor. The hole is preferably selectively exposed to a discharge pressure for a small portion of the cycle, and to an intermediate pressure for a second small portion of the cycle. Other than those two small portions, the hole is preferably closed. The invention reduces pulsation in the back pressure chamber and also reduces pumping losses caused by fluid moving into and out of the back pressure chamber through the hole. In one embodiment, grooves are formed in the fixed scroll member to communicate a selected intermediate pressure and a discharge pressure to locations on the base plate of the fixed scroll member. A vent hole in the wrap of the orbiting scroll member cyclically moves over the two grooves. The vent hole is closed by the base plate of the fixed scroll member for the majority of its operational cycle. In a second embodiment, a pair of holes are formed through the base plate of one of the scroll members. The holes are covered by the wrap of the other scroll member for the majority of the operational cycle of the scroll compressor. Each hole is open for a small portion of the operational cycle to selectively tap an intermediate and discharge pressure to the back pressure chamber.
摘要翻译：通过在涡旋压缩机的大部分操作循环中保持关闭通气孔来实现对涡旋压缩机中的背压室排出或抽吸的压力的改进控制。该孔优选地选择性地暴露于循环的一小部分的排出压力，并且优选地暴露于循环的第二小部分的中间压力。除了两个小部分之外，孔最好是封闭的。本发明减少了背压室中的脉动，并且还降低了流体通过孔进入和离开背压室所引起的泵送损失。在一个实施例中，在固定涡旋构件中形成槽，以将选定的中间压力和排出压力连通到固定涡旋构件的基板上的位置。绕动涡旋件的涡卷中的通气孔循环地移动到两个凹槽上。在其大部分操作周期中，通气孔由固定涡旋件的基板封闭。在第二实施例中，通过一个涡旋件的基板形成一对孔。在涡旋压缩机的大部分操作循环中，这些孔被另一个涡旋件的包裹物覆盖。每个孔在操作循环的一小部分打开，以选择性地分离中间体并将压力排出到背压室。

摘要： Oil retention recesses are formed in an outer periphery of the slider block of a scroll compressor. The recesses insure that a quantity of oil is captured and maintained during operation and after shutdown of the scroll compressor. If the scroll compressor is operated or started back up during a “starved” lubricant condition, the captured oil insures the scroll compressor can operate without damage for a period of time such that lubricant can be returned to the sealed compressor.

摘要： An improved scroll compressor has an orbiting scroll wrap that is designed to always be at most equal in height to the fixed scroll wrap. The orbiting scroll wrap is preferably designed shorter than the fixed scroll wrap by a distance equal to the manufacturing tolerances on the height of the two scroll wraps added together. In this way, the present invention insures that in no acceptable parts will the height of the orbiting scroll wrap exceed the height of the fixed scroll wrap. In a situation where the height of the orbiting scroll wrap does exceed the height of the fixed scroll wrap, there is a tendency to limit the stable operational envelope of the system. By insuring that the orbiting scroll wrap height is always at most equal to the fixed scroll wrap height, the present invention avoids this limitation on the operational envelope.

摘要： A compressor has an inlet, an outlet, and at least an intermediate first port therebetween. A condenser is coupled to the compressor to receive refrigerant. First and second evaporators are coupled to the condenser to receive refrigerant. Conduits define a return flowpath from the first evaporator to the compressor inlet and a second return flowpath from the second evaporator to the intermediate port. A bypass conduit extends between a first location between the first evaporator and the compressor inlet and a second location between the second evaporator and the first port.

摘要： An improved apparatus and method for injecting a liquid/vapor into compression chambers at an intermediate pressure utilizes the economizer injection ports already found in the compressor. By selectively communicating a liquid to be injected into the compression chambers to the economizer return line, the economizer return line and its ports are utilized for this liquid/vapor injection. In this way, no additional flow connections at the compressor are necessary. Moreover, by injecting the liquid at an intermediate pressure point, the other benefits are provided. In general, the liquid is injected to reduce the discharge temperature of the refrigerant under certain operational conditions.
