Abstract

The chain saw has a housing (11) with a cutting chain, supplied with lubricant via esp. a reciprocating piston lubricant pump (17). Intake and discharge pipes (21,22) of the pump are opened/closed via a single valve member (52), dependent upon the stroke direction of the pump piston (23). The valve member is an esp. circular disc membrane pref. of elastic material. An opening section of each of the pipes is formed as a valve seat, associated with either side of the membrane disc.
