The paper identifies that one of the primary sources of noise is pressure pulsation. Noise criteria is becoming increasingly significant in evaluating the feasibility of drive applications, especially micro-hydraulic drives. The noise issue is particularly relevant to micro-hydraulic systems, which are being increasingly used in vehicles and other modes of transport. To address this, the paper proposes a method for reducing pressure pulsations by integrating a chamber-type damper into a micro-hydraulic power pack system. Experimental tests results confirmed the high effectiveness of the damper within the selected frequency range. The paper also provides the theoretical basis for designing a chamber-type damper.
