摘要： Mechanical compression and vacuum release mechanisms for internal combustion engines. The compression and vacuum release mechanism may include a pair of centrifugally responsive flyweights pivotally mounted to the cam gear. One of the flyweights actuates a vacuum release member having a vacuum release cam and the other of the flyweights actuates a compression release member having a compression release cam. In another embodiment, the compression and vacuum release mechanism includes a single flyweight having structure associated therewith to actuate a vacuum release member and a compression release member having respective vacuum and compression release cams. The compression and vacuum release cams are in lifting engagement with the valve actuation structure of one of the intake or exhaust valves of the engine during engine starting to relieve compression and vacuum within the combustion chamber and thereby facilitate easier engine starting. After the engine is started and reaches running speed, centrifugal force causes the compression and vacuum release cams to move out of engagement with the valve actuation structure of the intake or exhaust valve to allow the engine to operate normally.

摘要： The eccentric on the crankshaft of a rotary compressor, as well as the roller that surrounds the crankshaft, is replaced by an elliptical cam that acts as a double eccentric. In this manner, the elliptical cam provides for proper balancing of the crankshaft and other components of the compressor, while eliminating the need to use counterweights. Specifically, the elliptical cam is symmetrical, resulting in equal forces acting on opposing sides of the elliptical cam. This allows the elliptical cam to maintain its balance throughout its rotation, even when operating at a high rate of revolution.
摘要翻译：
旋转式压缩机的曲轴上的偏心轮以及曲轴周围的滚轮由椭圆形凸轮代替，该椭圆形凸轮用作双偏心轮。以这种方式，椭圆形凸轮提供了曲轴和压缩机的其他部件的适当平衡，同时消除了使用配重的需要。具体而言，椭圆形凸轮是对称的，导致作用在椭圆形凸轮的相对侧上的相等的力。这使椭圆形凸轮在整个旋转过程中保持平衡，即使在高转速下工作也是如此。

摘要： An oil slinging device is provided in a compressor utilizing a centrifugal oil pump (50) to pump oil from a sump (58) in the bottom of the compressor upwardly through an axially disposed oil passage (60) in the crankshaft (18). The device is an elongated, rigid tube (68) connected to the upper end of the crankshaft and in communication with the oil passage, and is angularly disposed outwrdly in relation to the rotational axis of the crankshaft to dispose its remote upper end (70) upwardly and radially outwardly from the periphery of the rotating crankshaft. Oil pumped through the device by the oil pump is slung radially outwardly against the interior surfaces (73) of the compressor housing (12) in order to allow the oil to flow downwardly along the compressor housing inner surfaces, thereby cooling the oil by conducting heat energy therefrom to the compressor housing (12).

摘要： A motor control system (20) for a brushless and sensorless DC motor (22) for driving a compressor (28), pump or other application, includes a protection and fault detection circuit (42) for detecting a locked rotor (26) and a rotor which has stopped because of lost rotor phase lock. The motor control system also includes an off-theshelf motor control integrated circuit (40) having an input for disabling power outputs to the motor phase coils. The protection and fault detection circuit uses a back EMF sampling circuit (54) coupled to the motor phase coils (24a-24c) and momentarily disables power to the motor phase coils, via the motor control integrated circuit input, to determine if the motor rotor is rotating. The system also monitors supply voltage, supply current, temperature, and motor speed limits to detect faults and protect system components.

摘要： An integrated HVACR control and protection system (10) includes a modular and reprogrammable design providing a plurality of possible combinations of power detection, voltage detection, run current detection, transient current detection, temperature detection, universal thermostat interface, peripheral or remote control, and local display and control. The control and protection system is capable of evaluating the relationship between real power used by an HVACR system compressor (230, 330, 430) and other system operating parameters to detect problems early in the failure cycle, i.e., before a failure has progressed to requiring a system shutdown or causing damage to other components. Additionally, a control system (10) and method (500) provide sensorless detection of various HVACR system faults, such as, for example, loss of refrigerant or a refrigerant flow restriction, that impact the relationship between real power and current, voltage, temperature, or other operating parameters. Peripheral or remote control (160, 170) includes wired or wireless system monitoring and parameter programming using a personal digital assistant (PDA), for example utilizing IR communication between the PDA and the control and protection system.

摘要： A compressor terminal fault interruption method and interrupter for disconnecting power to a compressor terminal (20, 28) when terminal venting failure is imminent including a current sensing circuit (104) for sensing current provided to the terminal by a power source and outputting a sensed signal representing the current provided to the terminal and a control circuit (106). The control circuit includes a first circuit (102, 108) for outputting a reference signal representing input current much higher than locked rotor current, a second circuit (106) connected to the current sensing circuit and the first circuit for comparing the sensed signal to the reference signal, and a third circuit (RY1) connected to the second circuit for disconnecting power to the terminal when the sensed signal exceeds the reference signal, thereby preventing excessive current from reaching the compressor terminal (20, 28).
