  • Patent number: 10836235
    Abstract: A heating, ventilation and air conditioning (HVAC) system of a vehicle includes: an indoor air conditioning circuit which produces to supply cooling air to a vehicle interior by heat-exchanging inflow air through an indoor air inlet or an outdoor air inlet with an evaporator, and which produces to supply warm air to the vehicle interior or to discharge to the outside of the vehicle interior by heat-exchanging inflow air with a heat exchanger. The heat exchanger is connected with an engine cooling circuit so that engine coolant is used as a heat source of the heat exchanger, thereby improving the cooling performance of the ERG cooler.

  • Publication number: 20200269723
    Abstract: A cooling system of an electric vehicle is provided. The system includes an integral valve having at least one or more coolant inlets and at least two or more coolant outlets, and selectively discharges a coolant through one of the at least two or more coolant outlets. A plurality of coolant paths connected such that the coolant discharged through one of the at least two or more coolant outlets is introduced back into the integral valve through the at least one or more coolant inlets after being supplied to a portion where coolant circulation is required. A heat pump device is disposed in at least one or more of the plurality of coolant paths to selectively increase or decrease a temperature of the coolant.

  • Publication number: 20200274214
    Abstract: A cooling system of an electric vehicle includes: an integral valve with one or more coolant inlets and two or more coolant outlets, and which selectively discharges coolant through one of the coolant outlets; coolant paths that are connected with each other such that the coolant discharged through one of the coolant outlets is introduced back into the integral valve through the one or more coolant inlets after being supplied to a portion where coolant circulation is required; and a temperature controller that selectively controls a temperature of the coolant. The integral valve, at least a portion of the plurality of coolant paths, and the temperature controller may form one valve module.

  • Publication number: 20140079579
    Abstract: A high-pressure fuel pump apparatus may include a housing, a camshaft that may be mounted in the housing and rotated by operation of an engine, an eccentric cam that may be disposed eccentrically with respect to the camshaft and integrally rotated with the camshaft, a piston that may be slidably mounted in the housing and engaged to the eccentric cam to move up/down in the housing to produce a pressured fuel with rotation of the eccentric cam, and a rotary member that may be disposed between the eccentric cam and the piston and has a rolling contact with the eccentric cam and the piston to convert rotation of the eccentric cam into a straight motion of the piston.
