  • Patent number: 11913450
    Abstract: A scroll compressor includes a discharge guide disposed in a high-pressure part to guide refrigerant discharged from a compression part to a refrigerant discharge pipe, and the discharge guide may extend by a preset height from an inner circumferential surface of a casing constituting the high-pressure part toward one side surface of a high and low pressure separation plate. This can guide discharge refrigerant discharged to the high-pressure part to quickly flow to the refrigerant discharge pipe before being spread in an entire space of the high-pressure part, thereby preventing the high and low pressure separation plate from being overheated by discharge refrigerant of high temperature. This can result in preventing suction refrigerant of a low-pressure part from being heated by heat of discharge refrigerant transferred through the high and low pressure separation plate, thereby reducing a specific volume of the suction refrigerant and improving compressor efficiency.

  • Patent number: 11867299
    Abstract: A flow path switching valve is used in an engine water cooling system mounted on a mounting surface of an engine, and switches a flow path of a cooling water in the engine water cooling system. The engine water cooling system has a block jacket formed on a cylinder block and a head jacket formed on a cylinder head, connected to each other via a communication passage. The cooling water flowing in from an inlet of the block jacket flows into an inlet port of the flow path switching valve from an outlet of the head jacket via the communication passage. An inflow barrier plate is provided, which closes a part of a leak path side of the inlet port to suppress an inflow of the cooling water from the block jacket via a leak path made in the cylinder block and the cylinder head.

  • Patent number: 11073152
    Abstract: Disclosed herein may be a compressor. The compressor may include: a casing; a compression unit configured to suck refrigerant from a suction space of the casing, compress the sucked refrigerant, and discharge the compressed refrigerant to a discharge space of the casing; an oil recovery passage configured to recover oil separated from refrigerant in the discharge space to the suction space; and a reducer inserted into the oil recovery passage to reduce a pressure of oil passing through the oil recovery passage. The reducer may include a deformation preventing unit configured to prevent the reducer from being damaged when the reducer is inserted into the oil recovery passage. Therefore, the reducer may be prevented from being damaged when the reducer is inserted into the oil recovery passage. The costs required to prevent the reducer from being damaged, check the conditions of the reducer, and repair reducer may be reduced.

  • Patent number: 11000783
    Abstract: A chamber has a first opening, a second opening, and a third opening. The second opening is higher in level than the first and third openings, and is located at the highest position of a reservoir. Air bubbles are easily collected around the second opening, higher in level than the third opening, due to buoyancy. Moreover, the chamber includes an upper slope on an upper inner wall thereof such that a sectional area of the chamber becomes smaller toward the highest position of the reservoir. The upper slope causes the air bubbles not to stagnate but to be guided to the second opening along the upper slope. This makes easy discharge of the air bubbles from the chamber.
