Las bombas de vacío eléctricas de HELLA se utilizan para apoyar o generar únicamente el vacío para el sistema de servofreno neumático. En determinadas condiciones de conducción o según el diseño del motor, no se puede proporcionar suficiente vacío al servofreno a través del colector de admisión de un motor de combustión interna. La variante UP 28 puede apoyar el sistema generando un vacío adicional (aplicación de apoyo). Las UP 5.0 y UP 30 pueden proporcionar el suministro de vacío neumático por sí solas (aplicación "stand alone"). En este caso, la bomba actúa como la única fuente de vacío y garantiza un suministro suficiente para el servofreno y cualquier consumidor auxiliar. Estructura y función: El funcionamiento de las bombas de vacío se basa en el principio de compresión de paletas rotativas. La bomba contiene un rotor excéntrico con respecto a la cámara de la bomba. Las correderas incrustadas en el rotor se deslizan a lo largo de la pared interior de la cámara de la bomba. La rotación comprime continuamente el volumen encerrado por las correderas. Este cambio en el volumen de la celda genera un vacío con el efecto de que el aire es aspirado desde el servofreno a través del sistema de tuberías neumáticas del sistema de frenos por la bomba de vacío.

This company lies to you. Ordered a 02 sensor from APPD for my C7 Vette. Paid the highest possible courier service for the fastest possible shipping from Newcastle to France. I needed the part urgently. Ordered at the weekend and called them Monday to confirm all was in hand and explained the part was required urgently. Response from APPD yes we've recieved the order and will ship as soon as its been processed. Called every day for the next 7 days to be told yes its been shipped and this is the shipping number. Turned out it took them till Friday ..5 days later to post it and then the package lay at the courier another week or so. APPD lied to me throughout this whole transaction. The package cleared customs in 2 days and should have been with me in just over week and not over 4 weeks. APPD offereed the postage refunded after I had to start a PAYPAL dispute.. This should have been a straight forward simple part delivery.When it goes wrong you shouldn't lie to your customer. A serious compay would refund the customer not try to fuzz the truth and blame everyone else. I refused the postage delivery refund so you can buy some honesty pills and discuss with your team how to avoid more negative service feedback. If your thinking of ordering parts from APPD scroll on and find another supplier. You dont need or want the hassle of dealing with these people.

Over a month waiting on parts and all I get is it will scan soon week after week. Reordered from US so I could finish build and same parts arrived in one week. Waiting to see if they will refund??

placed an order for parts 13th of feb, all listed in stock, got shipping update for label created on the 16th of feb. I have still not received what I ordered and paid for, no updates. I have been getting the same generic answer "order will be fulfilled today" for nearly 2 months now when trying to enquire. Quite disappointing as I have been unable to finish off my car due to waiting on the final fuel system parts for over 2 months now.
