Temperature sensitive solenoid valve in a scroll compressor

Title TEMPERATURE SENSITIVE SOLENOID VALVE IN A SCROLL COMPRESSOR Inventors David H. Eber Peter A. Kotlarek Ronald W. Okoren Abstract Inside the hermetic shell of a scroll compressor, a normally closed solenoid valve seats against the back side of a stationary scroll plate to close a discharge opening through the plate. A coil circuit that actuates the valve has an electrical resistance that increases with temperature. The temperature dependent resistance allows the coil circuit to also function as a discharge temperature sensor. Should the discharge gas over-heat, the compressor motor and the valve are de-energized in response to the resistance exceeding a predetermined limit. The closed valve prevents backflow from rapidly reversing the rotational direction of the compressor, which can be extremely noisy and damaging to the compressor. Both the valve and the compressor motor are energized at the same time, regardless of the compressor's direction of rotation. Should the compressor motor be inadvertently wired to operate in reverse, the solenoid valve still opens to prevent destructively low pressure from developing between the scroll plates.

Apparatus preventing reverse revolution for scroll compresser

본 발명은 스크롤 압축기의 역방향 운전방지장치에 관한 것으로, 스크롤 압축기의 가변반경 구조를 구성하는 크랭크축과, 이 크랭크축의 편심부와 선회스크롤의 중심부 사이에 삽입되는 슬라이드 부시에 서 정회전시의 운전면이 크랭크축의 중심과 선회스크롤의 중심을 연결하는 기준선과 이루는 정회전시의 운전 각도에 비하여 역회전시의 운전면이 상기 기준선과 이루는 역회전시의 운전 각도를 소정값 이상으로 크게 하여 선회스크롤의 고정스크롤과의 마찰을 증가시켜 압축기의 역방향 운전이 방지되도록 구성된다. 이러한 스크롤 압축기의 역방향 운전방지장치는 3상 전원을 사용하는 스크롤 압축기에 있어 제품의 설치 시 발생하기 쉬운 각 상 전원의 오결선으로 인한 압축기의 역회전에 의한 손상을 역회전 시 선회스크롤과 고정스크롤의 마찰력을 압축기의 기동 부하 보다 크게 하여 역방향 운전을 방지할 수 있는 이점이 있다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing the reverse operation of a scroll compressor, and includes a crank shaft constituting a variable radius structure of a scroll compressor, and an operating surface at the time of forward rotation in a slide bush inserted between the eccentric portion of the crank shaft and the center of the turning scroll. Fixing the turning scroll by increasing the driving angle at the time of reverse rotation that the driving surface at the reverse rotation makes with the reference line more than the predetermined value, compared to the driving angle at the forward rotation formed with the reference line connecting the center of the crankshaft and the center of the turning scroll. It is configured to prevent the reverse operation of the compressor by increasing the friction with the scroll. The reverse operation prevention device of the scroll compressor is a scroll compressor using a three-phase power source, and the rotating scroll and the fixed scroll can be used to prevent damage caused by reverse rotation of the compressor due to incorrect wiring of each phase power source, which is likely to occur when the product is installed. There is an advantage that the frictional force of greater than the starting load of the compressor can prevent the reverse operation.

SPIRAL COMPRESSOR WITH BEARING LUBRICATION CIRCUIT

Scroll compressor with discharge valve opened by centrifugal force

A scroll compressor, having a first scroll member and a second scroll member, includes a discharge valve device for closing an opening of a discharge port in which the discharge opening is disposed in at least one of the first and second scroll members. The discharge valve device is configured so that it is effected by a centrifugal force during operation of the scroll compressor. The centrifugal force normally maintains the discharge valve device in an open position with respect to the discharge opening. Thus, the discharge valve device is not actuated by a pressure chamber and the scroll members are not rotated in reverse when operation of the scroll compressor is stopped.

FUEL TRANSFER ASSEMBLY FROM A FUEL TANK

Reverse phase and high discharge temperature protection in a scroll compressor

A low side scroll compressor (20) is protected from both the potentially damaging effects of improper electrical hookup and the development of high discharge temperatures by the disposition of a valve member (48) in a passage (46) which communicates between the suction pressure portion (38) and a discharge pressure portion (36) of the compressor. The valve (48) operates to permit the flow of gas from the suction to the discharge pressure portion of the compressor through a protective passage when the compressor is caused to run backwards due to miswiring so as to avert damage to the scroll members (24, 30). The valve permits the flow of gas from the discharge to the suction pressure portion of the compressor through the protective passage when the temperature of the discharge gas produced by the compressor is caused to exceed a predetermined temperature. The resulting flow causes the compressor motor to de-energize.

Check valve with an inertial mass for progressive cavity pumps

The invention concerns a check valve with an inertial mass which is fitted in the base of the production tubing and above the progressive cavity pump (PCP) of an oil well, said valve preventing the hydrostatic column within the production tubing from falling at the moment at which the artificial rise of said column stops as a result of the PCP stopping. Preventing this phenomenon from occurring prevents the PCP from rotating in the sense opposite to that of its normal operation and from becoming blocked by particulate material deposited therein.

Reverse rotation detection for compressors

A method is disclosed for identifying when a compressor is being run in reverse due to improper wiring. In a preferred embodiment, sensors sense the condition of a refrigerant at the inlet line and a refrigerant at the outlet line. If an expected pressure differential is not seen, then the determination is made that the compressor is running in reverse. In embodiments the control system may shut down the compressor, provide an alarm, or reverse a phase of two of the three wires of a three phase power input to correct the rotation direction.
