  • Patent number: 9605629
    Abstract: An under-hood mounting configuration for a work vehicle may generally include an air intake component positioned upstream of an engine of the work vehicle. The air intake component may include a wall having an exterior surface and an interior surface. The wall may define a cooling port extending between the exterior surface and the interior surface. In addition, the under-hood mounting configuration may include a control unit having a housing defining an upper surface and a lower surface opposite the upper surface. The housing may be mounted to the wall along the exterior surface such that the housing is positioned directly over at least a portion of the cooling port. When the airflow is directed through the air intake component, a portion of the airflow may flow through the cooling port and may be directed towards the lower surface of the housing.

  • Patent number: 9546646
    Abstract: A combined pump-injector valve utilizing a single piece as the barrel of the pump and as the stator of the valve, thus eliminating any need for connections between a pump and a valve, and therefore the potential for high-pressure leaks or pressure reductions. The combined pump-injector valve permits injection of nanoliter-sized samples into a chromatographic column, which is sealed during loading of the sample and filling of the pump, such that complete analyses can be completed with microliters of mobile phase with nanoliters of a sample.

  • Patent number: 9545032
    Abstract: An enclosure includes a housing defining an interior chamber for receiving an electronic assembly. The housing is made of a thermally conductive material so as to operate as a heat sink. The housing has a heat transfer surface within the interior chamber for receiving heat generating components thereon, and an interior groove within the interior chamber. The enclosure also includes a retaining clip having a clip length, a first portion extending along the clip length for engaging the interior groove, and a second portion extending along the clip length for engaging the heat generating components. The retaining clip is made from a resilient material and is sized and shaped such that positioning the first portion in the interior groove flexes the retaining clip and presses the second portion against the heat generating components so as to bias the heat generating components into thermal contact with the heat transfer surface.

  • Patent number: 9506395
    Abstract: A cooling system for a supercharged internal combustion engine may include a charge air cooling circuit, in which a low-temperature coolant circulates and which may have a low-temperature charge air cooler for cooling charge air and a low-temperature coolant cooler for cooling the low-temperature coolant. The system may include a refrigerant circuit, in which a refrigerant circulates and which has a vaporizer for vaporizing the refrigerant and a condenser for condensing the refrigerant. The system may include a coupling heat exchanger for a fluidically separated, heat-transmitting coupling of the charge air cooling circuit with the refrigerant circuit. The coupling heat exchanger may be arranged in a vaporizer bypass of the refrigerant circuit thereby bypassing the vaporizer and be arranged in a coupling branch of the charge air cooling circuit. The coupling branch may branch off via a branching-off point from a feed of the charge air cooling circuit.
