An apparatus is provided for cooling a high heat-generating vehicle component having a coolant loop. The apparatus comprises an air compressor assembly including a heat-sinking portion that can be thermally coupled to the coolant loop to transfer heat energy away from the coolant loop to enhance cooling of the vehicle component.

An integrated flow control valve apparatus configured to control a flow rate of coolant in an engine cooling system for cooling an engine may include a cylinder block and a cylinder head mounted above the cylinder block, the integrated flow control valve apparatus may include a valve housing; a plurality of coolant ports formed at the valve housing and provided as inlets and outlets through which the coolant flows into and out of the valve housing; and valves configured for opening and closing the coolant ports, wherein the coolant ports include a first inlet port for introduction of the coolant from the cylinder block and a second inlet port for introduction of the coolant from the cylinder head into the valve housing; and the flow of the coolant at the first and second inlet ports is controlled by the valves configured to vary the flow of the coolant in the cylinder block and the cylinder head.

A hybrid propulsion system includes a heat engine configured to drive a heat engine shaft. An electric motor configured to drive a motor shaft. A transmission system is connected to receive rotational input power from each of the heat engine shaft and the motor shaft and to convert the rotation input power to output power. A first lubrication/coolant system is connected for circulating a first lubricant/coolant fluid through the heat engine. A second lubricant/coolant system in fluid isolation from the first lubrication/coolant system is connected for circulating a second lubricant/coolant fluid through the electric motor.

A temperature responsive valve includes a housing and a cylindrical structure disposed within the housing. The housing defines an inlet passageway and an outlet passageway wherein the cylinder body of the cylindrical structure is disposed between the inlet passageway and the outlet passageway. The cylindrical structure includes a first layer so that the cylindrical structure is configured to expand from a decreased diameter to an increased diameter when the first layer of the cylindrical structure is exposed to an increased pre-determined temperature range causing the cylindrical structure restricts the inlet passageway and the outlet passageway at such increased pre-determined temperature range.

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 assembly for a turbine engine having an oil circuit. The oil circuit includes an air/oil heat exchanger, a primary bypass pipe connecting an intake of the air/oil heat exchanger to an outlet of the air/oil heat exchanger and surrounding the air/oil heat exchanger so as to exchange heat with the air/oil heat exchanger. The oil circuit further includes and a secondary bypass pipe of the primary pipe connecting the upstream end of the primary bypass pipe to the downstream end of the primary bypass pipe. The oil circuit also includes at least one valve for controlling the passage of the flow of oil into the primary and secondary bypass pipes and means for controlling the opening of said at least one valve for a temperature lower than a threshold temperature.

A valve system is disclosed herein. The valve system, in one arrangement, may comprise: a fluid pathway for transporting a fluid; a first valve operably coupled to the fluid pathway, the first valve comprising a first resilient element; a second valve operably coupled to the fluid pathway, the second valve comprising a second resilient element that is substantially identical to the first resilient element; wherein, when the first valve is in a closed state, the first resilient element is compressed to a first length so that the first valve opens at a first pressure; and wherein, when the second salve is in a closed state, the second resilient element is compressed to a second length so that the second valve opens at a second pressure, the first length is less than the second length such that the second pressure is less than the first pressure.

Apparatuses, systems, and methods are disclosed to prime a refrigerant pump by decoupling the condenser from the refrigerant pump and the refrigerant pump line or shielding from a condenser operation prior to startup of the system, so that liquid refrigerant can be appropriately sourced from the condenser and/or the evaporator using flow control device(s) such as a source valve on a source line of the condenser and/or on a source line of the evaporator and the control of such valve(s).

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.

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.
