Abstract

PURPOSE:To reduce a power unit body in size and raise silencing effect by providing a hydraulic muffler outside the unit with the lengths of the pipes between the unit, a control valve and a pump set proper for the pressure pulsation absorption of the muffler. CONSTITUTION:A hydraulic muffler 9 is provided outside, longitudinally of, a power unit body 1, and connected with a control valve connected to the discharge side of a pump by means of a unit inside pipe 8, a flexible pipe 8' and an outside pipe 8''. The pipes 8' and 8'' are passed outside of the unit 1 and fastened on a support table fastened on a base. Thereby, the lengths of the pipes between a hydraulic muffler, a control valve and a pump can be made proper for the pressure pulsation absorption of the muffler, the silencing effect of the muffler becomes large, and the unit body can be reduced in size.
