Abstract
ESTRUTURA PARA SENSORIAMENTO DA VELOCIDADE DE FLUXO DE REFRIGERANTE EM UM COMPRESSOR. é mostrado um compressor conectado a um circuito externo de refrigerante. O compressor é equipado com um alojamento, um membro formador de passagem acoplado a uma superfície externa do alojamento e um detector de velocidade de fluxo do tipo de pressão diferencial provido no membro formador de passagem. O detector de velocidade de fluxo obtém a pressão na passagem anterior e a pressão na passagem posterior para detectar a velocidade de fluxo do refrigerante dentro da passagem de refrigerante. O detector de velocidade de fluxo é dotado de uma câmara de acomodação, um corpo de partição, uma mola de compressão e uma sede de mola que define a quantidade máxima de curso do corpo de partição. A sede de mola localiza-se mais perto do lado do membro formador de passagem do que de uma superfície de partição que divide o alojamento e o membro formador de passagem, e está em contato com a superfície de partição.
