Abstract

The present invention provides an automotive orbiter compressor comprising: a fixed cylinder having a suction passage formed to guide refrigerant flowing in from the outside into the inside, discharging the introduced refrigerant, and having a suction auxiliary groove formed on the bottom of the cylinder; a protrusion formed protruding inside the fixed cylinder; an orbiter cylinder installed to pivot inside the fixed cylinder and having an insertion groove formed on one side; and a cylinder block inserted into the insertion groove and movably installed between the fixed cylinder and the protrusion. The suction auxiliary groove moves the refrigerant inside the orbiter cylinder. According to the automotive orbital compressor, the suction auxiliary groove is formed so that the refrigerant flowing in from the outside flows smoothly into an inner chamber disposed inside the orbiter cylinder located inside the compressor, thereby preventing a decrease in the suction efficiency and volumetric efficiency of the compressor.

Description

차량용 오비터 압축기{Automotive Orbiter Compressor}Automotive Orbiter Compressor {Automotive Orbiter Compressor}

본 발명은 차량용 오비터 압축기에 관한 것으로, 더욱 상세하게는, 외부에서 유입된 냉매를 압축기하기 위해 실린더 내부의 작동공간에 오비터가 배치되고, 상기 오비터가 선회운동을 하여 상기 실린더 내부에 압축실을 형성하는 차량용 오비터 압축기에 관한 것이다.The present invention relates to an orbiter compressor for vehicles, and more particularly, an orbiter is disposed in a working space inside a cylinder to compress refrigerant introduced from the outside, and the orbiter rotates to compress the inside of the cylinder. It relates to an orbiter compressor for a vehicle forming a seal.

일반적으로 압축기로 가장 널리 사용되고 있는 왕복동식 압축기는 피스톤의 왕복운동을 이용하여 가스를 압축하는 방식으로 압축된 가스의 토출이 피스톤 왕복운동 1회당 1번 발생한다.In general, a reciprocating compressor, which is most widely used as a compressor, compresses gas using the reciprocating motion of a piston, and discharge of the compressed gas occurs once per piston reciprocating motion.

이러한 간혈적인 토출 특성으로 인해 가스의 맥동과 소음이 수반되며, 구동 동력과 또는 구동부와 연결된 회전축의 회전운동을 피스톤의 왕복운동으로 바꾸어 주는 과정에서의 불균형력이 발생하므로 진동을 피할 수 없다.Due to this intermittent discharge characteristic, gas pulsation and noise are accompanied, and vibration is unavoidable because unbalanced force occurs in the process of converting the driving power or the rotational motion of the rotating shaft connected to the driving unit into the reciprocating motion of the piston.

또한, 왕복동식에서는 흡입 및 토출 밸브의 채용이 불가피하여 압축비가 높은 경우 체적효율이 급감하고 에너지 소모가 커지게 된다.In addition, in the reciprocating type, the adoption of suction and discharge valves is unavoidable, and when the compression ratio is high, the volumetric efficiency sharply decreases and energy consumption increases.

이러한 왕복동 압축기의 단점으로 인해 새로운 작동방식의 압축기들이 많이 제안되었다.Due to the disadvantages of these reciprocating compressors, many compressors with new operation methods have been proposed.

이러한 새로운 개념의 압축기 가운데 하나로 선회운동하는 압축기구, 즉 오비터 압축기가 제안되었다.As one of these new concept compressors, a rotational compression mechanism, that is, an orbiter compressor, has been proposed.

도 1을 참조하면, 종래기술의 오비터 압축기(1)에 관한 것으로, 오비터 압축기는 경판 후면에 올담링(Oldham)과 같은 자전방지 기구를 적용하면 크랭크축(10) 회전에 따라 선회베인(오비터)(20)은 환형의 실린더(30) 내에서 선회운동하게 된다.Referring to FIG. 1, it relates to an orbiter compressor 1 of the prior art. When an anti-rotation mechanism such as an Oldham ring is applied to the rear surface of the head plate, the orbiter compressor rotates the turning vane according to the rotation of the crankshaft 10 ( Orbiter) (20) rotates within the annular cylinder (30).

오비터 압축기(1)의 작동원리를 살펴보면, 선회베인(오비터)(20)을 환형의 실린더(30) 내에서 운동하도록 위치시키면, 환형의 실린더(30) 내벽면과 선회베인(오비터)(20)의 외벽, 그리고 돌출부의 외측면과 선회베인(오비터)(20)의 내면 사이에 압축실(30a)들이 형성되며, 상기 압축실(30a)에는 흡입유로(F1)가 형성된다. 여기서, 선회베인(오비터)(20)의 선회운동에 따라 이들 압축실(30a) 내의 가스는 흡입-압축-토출 과정을 거치게 된다.Looking at the operating principle of the orbiter compressor (1), if the orbiter (orbiter) 20 is positioned so as to move within the annular cylinder 30, the inner wall surface of the annular cylinder 30 and the orbiter vane (orbiter) Compression chambers 30a are formed between the outer wall of the 20, the outer surface of the protrusion and the inner surface of the orbiter 20, and the suction passage F1 is formed in the compression chamber 30a. Here, the gas in these compression chambers 30a undergoes a suction-compression-discharge process according to the orbital motion of the orbiting vane (orbiter) 20 .

여기서, 미설명 부호 40은 냉매가 흡입되는 흡입구이며, 50은 인버터가 설치되는 인버터부이다.Here, reference numeral 40 denotes a suction port through which refrigerant is sucked, and 50 denotes an inverter unit in which an inverter is installed.

이러한 압축방식은 연속적이므로 가스 맥동이 거의 없고, 왕복운동하는 메카니즘이 없으므로 소음과 진동이 크게 감소하며, 흡입밸브가 없는 구조이므로 흡입밸브 통과 손실이 없다.Since this compression method is continuous, there is almost no gas pulsation, and since there is no reciprocating mechanism, noise and vibration are greatly reduced.

또한, 선회베인의 내,외 양쪽에 압축실(30a)들이 형성되므로 공간 활용이 높아져 압축기의 소형화를 이룰 수 있다.In addition, since the compression chambers 30a are formed on both the inside and outside of the turning vane, space utilization is increased and the compressor can be miniaturized.

종래의 오비터 압축기는 오비터 실린더를 기준으로 안쪽과 바깥쪽 압축챔버가 구분되어 있는 특징으로 종래의 오비터 압축기는 이 두 개의 챔버와 동시에 연통되는 큰 흡입유로를 구비하였다. 이는 전동식이 아닌 기계식 구조를 사용하여 흡입냉매가 모터실(흡입실)을 지나치지 않아도 되는 구조를 가지고 있기 때문이다. 하지만, 차량용 오비터 압축기는 모터와 인버터 냉각을 위하여 모터실(흡입실)에 냉매가 유입되어야 하므로 종래의 오비터 압축기와 다른 흡입유로를 구비해야 되는 문제점이 있다.Conventional Orbiter compressors are characterized in that inner and outer compression chambers are divided based on the Orbiter cylinder, and the Conventional Orbiter compressor has a large suction passage that communicates with these two chambers at the same time. This is because it has a structure in which the suction refrigerant does not have to pass through the motor chamber (suction chamber) by using a mechanical structure rather than an electric one. However, since the refrigerant must flow into the motor room (suction chamber) for cooling the motor and the inverter, the vehicle orbiter compressor has a problem in that it has to have a suction flow path different from that of the conventional orbiter compressor.

As shown in FIG. 4, the fixed cylinder 110 and the orbiter cylinder 130 perform a pivoting motion to compress the refrigerant introduced from the outside. This will be described in more detail as follows.
