MULTI-FREQUENCY PULSATION ABSORBER AT CYLINDER VALVE CAP |
摘要 |
A multi-chambered pulsation absorber for attachment over the valve cap opening of a compressor cylinder. Each chamber is in fluid communication with the valve cap opening (or cylinder internal gas passages) via an associated choke tube. Each pairing of a chamber with a choke tube is tuned, in the manner of a Helmholz resonator, to attenuate and nearly eliminate a different cylinder-related pulsation frequency, such as those resulting from internal cylinder pulsations or cylinder nozzle pulsations.
