摘要：
A muffler for attenuating pulsations within the hydraulic fluid of an hydraulic elevator includes a plurality of compressible elements for absorbing pressure pulsations within the fluid and a baffle for ensuring that the flow of fluid contacts the elements sufficiently to absorb such pulsations, the baffle allowing a certain amount of flow to pass therethrough so that the pressure drop around the baffle is not so extreme so as to cause the muffler to cease to function.
