An internal oil filter is installed at least partially inside a crankcase and/or an oil sump of a compressor. The internal oil filter can receive oil from an oil pressure regulator and filter the oil via filter media. The received oil radially penetrates through the filter media and flow directly into the oil sump from an outside surface of the filter media. This can eliminate the need of fluid lines connecting an outlet of an oil filter to the oil sump and any sealing mechanism therebetween.

A gasket in a transport refrigeration system (TRS) and method of preventing corrosion in a compressor using a gasket. The gasket includes a body, where the body includes a fluid pass portion, and a flange that extends from the body. The body and the flange include a second layer between an outside first layer and a third layer. The second layer is a metal and the metal is a non-uniform thickness that extends across the flange and the body to deflect compression load distribution.

Compressor gasket and method of preventing corrosion

A horizontal suction accumulator generally includes a tank, an inlet tube, and an outlet tube. The tank extends in a horizontal direction and is configured to receive a refrigerant. The refrigerant includes a vapor and a liquid. The tank stores the liquid refrigerant and discharges the vapor refrigerant. The inlet tube supplies into the tank an inlet stream that includes the liquid and vapor refrigerants. The inlet tube extends into the tank and is bent upward at an acute angle. The liquid refrigerant is stored in the tank. The vapor refrigerant is discharged through the outlet tube, which extends offset from the inlet tube and into the tank. The inlet tube defines an inlet opening positioned at a first elevation, the outlet tube defines an outlet opening positioned at a second elevation, and the first and second elevations are substantially the same.

Refrigeration system

An engine starter system that predicts when starter failure is imminent. The engine starter system monitors engine starter crank speed, battery voltage and ambient air temperature. The crank speed, battery voltage and ambient air temperature are communicated to a controller which compares the crank speed for the measured battery voltage and air temperature to a predicted crank speed for the measured battery voltage and air temperature. If the crank speed is lower than the predicted crank speed, a signal is sent to an alarm.

Engine starter predictive maintenance system

A method and apparatus for approximating the life of a gasket used in a predetermined environment is provided which allows for the long-term exposure to the environment to be simulated over a shortened period of time. The method and apparatus utilize the steps of placing a gasket sample in a test assembly, clamping the gasket sample within the test assembly at a predetermined clamping pressure whereby a chamber is formed within the interior of the gasket sample, filling the chamber with a gas at a predetermined pressure from a gas fill system, changing the temperature of the gasket sample over a predetermined number of temperature cycles, and measuring the amount of the gas which leaks from the chamber. The apparatus may also include a pressure control system for changing the pressure within the chamber over a predetermined number of pressure cycles or in response to predetermined temperature conditions.
