    Abstract: A scroll compressor includes a casing having an oil storage space, a fixed scroll disposed inside the casing, an orbiting scroll disposed on one side of the fixed scroll and performing an orbiting motion relative to the fixed scroll so as to form a compression chamber, a discharge cover coupled to another side opposite to the one side of the fixed scroll and having a cover bottom surface, and an oil feeder coupled to the cover bottom surface to face a direction opposite to the fixed scroll, to communicate with the oil storage space. The cover bottom surface is disposed at an inner side of an inner circumference of the oil feeder and defines a discharge hole to communicate with the inner side of the oil feeder.

    Abstract: A scroll compressor is provided that may include a casing, a main frame, a rotational shaft, an orbiting scroll, a fixed scroll, and an oil supply guide. A second oil supply guide of the oil supply guide may be disposed in at least one of the orbiting scroll or the fixed scroll and extend along a thrust bearing surface between the orbiting scroll and the fixed scroll to provide communication between a first oil supply guide and a compression chamber having a lower pressure than an oil storage space. This may produce a great pressure difference between ends of an oil supply passage including the first oil supply guide and the second oil supply guide, and allow smooth oil supply using differential pressure to the thrust bearing surface between the fixed scroll and the orbiting scroll.

    Abstract: A linear compressor includes a cylinder that defines a compression chamber configured to accommodate refrigerant and that includes a cylinder nozzle configured to receive refrigerant, and a piston provided in the cylinder and configured to be pressed by refrigerant in the cylinder. The piston includes a piston body configured to move forward and backward within the cylinder, a piston front part located on a front surface of the piston body, the piston front part comprising a suction port through which refrigerant is supplied into the compression chamber, and a refrigerant collection part that is recessed from an outer circumferential surface of the piston front part, that extends to a front surface of the piston front part, and that is configured to receive at least a portion of refrigerant compressed in the compression chamber.

    Abstract: A scroll compressor is provided in which a boss of an orbiting scroll is inserted into and coupled to a boss coupling recess of a crank shaft, so that friction loss of a bearing portion of the crank shaft may be reduced, compression efficiency and reliability of the compressor may be enhanced, and noise and material costs may be reduced. A bush bearing may be formed as a coating on the boss of the orbiting scroll, so that a thickness of the bearing portion of the crank shaft may be reduced. Since an outer circumferential surface of the bearing portion is in contact with an inner circumferential surface of the boss coupling recess, damage to the bearing portion may be prevented.

    Abstract translation: 提供一种涡旋压缩机，其中绕动涡旋盘的凸台插入并联接到曲轴的凸台联接凹槽，使得曲轴的轴承部分的摩擦损失可能降低，压缩效率和可靠性 可以增强压缩机，并且可以降低噪声和材料成本。 衬套轴承可以形成为绕动涡旋盘的凸台上的涂层，使得可以减小曲柄轴承部分的厚度。 由于轴承部的外周面与凸台接合凹部的内周面接触，所以可以防止对轴承部的损伤。

    Abstract: A fluid compressor includes a case, a fixed scroll, an orbiting scroll, a motor, and at least one anti-rotation unit. The case is configured to form an external appearance thereof. The fixed scroll is fixed in the case. The orbiting scroll is engaged with the fixed scroll at one side of the fixed scroll, and performs partitioning of a compression chamber. The motor provides the orbiting scroll with drive power. The anti-rotation unit is coupled to a side surface of the orbiting scroll so as to prevent rotation of the orbiting scroll.
