Abstract: A first lube oil is stored by a lube oil reservoir. The first lube oil is flowed from the lube oil reservoir through a tubing network connected to a crankcase of a reciprocating compressor. A second lube oil is stored by a cylinder lubricator oil reservoir. The second lube oil is flowed from the cylinder lubricator oil reservoir to a cylinder lubricator that is connected to cylinders of the reciprocating compressor. A liquid level in the cylinder lubricator oil reservoir is measured. Based on the measured liquid level, at least a portion of the first lube oil from the tubing network is flowed to the cylinder lubricator oil reservoir through an intermediate flowline connecting the tubing network to the cylinder lubricator oil reservoir.

Abstract: A compressor crankcase heating control method for a heat pump system includes selectively actuating a first switching device to connect and disconnect first and second power lines to and from second and third switching devices, respectively, the first and second power lines receive a first voltage. The compressor crankcase heating control method further includes, when the first and second power lines are disconnected from the second and third switching devices via the first switching device, actuating the second and third switching devices thereby connecting third and fourth power lines to ends, respectively, of at least one winding of a stator of an electric motor of a compressor. The at least one winding of the stator of the electric motor heats the crankcase of the compressor. The third and fourth power lines receive a second voltage that is less than the first voltage.

Abstract: Method and equipment to control operating temperature of an air compressor. A compressor element compresses air and oil and supplies it to an oil separator. In the separator, the air and oil are separated. Oil is led to a circulating pipe and returned to the compressor element. When necessary, at least some of the oil flowing in the oil circulating pipe is supplied to cooling, which is used for controlling operating temperature of the compressor such that it is as low as possible, but nevertheless so high that no condensation point is reached. The amount of oil to be supplied to cooling is controlled by a thermostatic valve based on a change in dimension of a controlling element such that dimensions of the controlling element are changed by an external command.

Abstract: A device and method are described for extending the life of check valves. An improved check valve having a double poppet and tapered guides is more robust, and a check valve protection device between the check valve and the environment into which fluid is injected protects the valve from a contaminating or corrosive environment. The check valve and check valve protection device are small and light weight to prevent vibration-induced failures. The check valve protection device preferably has an interior volume that fills quickly by relatively few cycles of the lubricant pump to reduce delay of lubricant to the injection point.
