Generally, apparatuses, systems, and methods are described that are directed to accessing liquid refrigerant from an evaporator to source a refrigerant pump and pump line to cool and lubricate such moving parts that may be part of the compressor, for example the compressor motor and the compressor bearings, and/or for cooling drives such as an adjustable or variable frequency drive.

An outboard motor includes an engine, a cooling water passage, a pump that is driven in conjunction with the engine, an inlet water passage that branches from the cooling water passage, an oil cooler, an outlet water passage, a first thermostat located in the cooling water passage, and a second thermostat. The pump takes outside water into the cooling water passage. The oil cooler includes a water-storing space into which water in the inlet water passage is taken. The outlet water passage is connected to an outlet of the oil cooler. The first thermostat increases and decreases the flow rate of water flowing through the engine. The second thermostat is located at the outlet or at the outlet water passage, and increases and decreases the flow rate of water flowing through the outlet water passage.

Certain exemplary embodiments can provide a system comprising an oil filter adapter constructed to be installed between an engine of a motorcycle and an oil filter of the motorcycle. The oil filter adapter defines an oil inlet aperture and an oil outlet aperture. The system comprises a heat exchanger, which defines an oil inlet port and an oil outlet port.

An internal combustion engine, which can improve an annual energy consumption efficiency, is provided. A gas engine 1 includes: an oil cooler 11 having a passage via which heat is exchanged between engine cooling water and lubricating oil; and a control unit 12 configured to control a temperature of the engine cooling water to a constant temperature so as to cool the lubricating oil during high load operation and to heat the lubricating oil during low to medium load operation. The control unit 12 increases the temperature of the engine cooling water during low to medium load operation compared with the temperature of the engine cooling water during high load operation. An oil jet 18a, which is configured to inject the lubricating oil into a rear surface of a piston 17, is provided.

An oil circulation system of an internal combustion engine comprises a first oil pan and second oil pan, first oil supplied parts supplied with oil stored in the first oil pan, second oil supplied parts supplied with oil stored in the second oil pan, and a heating part. The heating part has oil paths through which oil flows and heats the oil flowing through the oil paths. The oil circulation system comprises a first circulation path circulating oil through the first oil pan, heating part, and first oil supplied parts, and a second circulation path circulating oil between the second oil pan and the second oil supplied parts.

An oil cooler may include at least two heat exchanger plates stacked in a stacking direction, and a cover plate. A fluid channel may extend between the cover plate and the adjacent heat exchanger plate. A thermostatic valve may be connected to the fluid channel in a fluid-transmitting manner via a thermostatic valve housing of the thermostatic valve. The cover plate may include at least two connecting pieces or an adapter plate may be arranged between the cover plate and the thermostatic valve housing and may include at least two connecting pieces. The thermostatic valve housing may include at least two connecting pieces configured complementary to the at least two connecting pieces of the cover plate or the adapter plate, and secured therein. The at least two pieces of the thermostatic valve housing may be soldered in the at least two connecting pieces of the cover plate or the adapter plate.

Disclosed is a hydraulic pressure supply system of an automatic transmission for a hybrid vehicle. A hydraulic pressure supply system of an automatic transmission for a hybrid vehicle pumps oil stored in an oil pan using an oil pump to supply the oil to a high pressure part and a low pressure part. The hydraulic pressure supply system includes a separate motor/generator cooling route which uses an oil flow recirculated in a line regulator valve and an another oil flow recirculated in a reducing valve.

An oil filter housing system comprising a housing body. The housing body defines an integral coolant supply passage in fluid supplying communication with a coolant pump. The housing body further defines an integral coolant volute in fluid receiving communication with the coolant pump. The housing body defines an oil cooler cavity configured to house an oil cooler, a first integral oil flow passage in fluid supplying communication with the oil cooler, and a second integral oil flow passage in fluid receiving communication with the oil cooler. A third integral oil flow passage is in fluid supplying communication with a turbocharger. An angled oil filter interface is coupled to the housing body and is configured to receive an oil filter, the oil filter in fluid supplying communication with the third integral oil flow passage.

Generally, apparatuses, systems, and methods are described to vent refrigerant vapor from the refrigerant pump line using a vent line, such as during priming of the pump and/or during a startup of the compressor, directed to a relatively reduced volute casing mass of the refrigerant pump, and/or directed to returning refrigerant to an economizer or chiller component other than the condenser.
