CHAIN FLUID PUMP FOR A POWER CHAIN SAW AND POWER CHAIN SAW COMPRISING SUCH A CHAIN FLUID PUMP

摘要

The invention relates to a chain fluid pump (20) for a power chain saw (10), which chain fluid pump (20) takes up the chain fluid through a suction line (29) from a tank (22) and feeds it through a pressure line (27) to a saw device (12) of the power chain saw (10). To allow for the chain fluid pump to be switched off in a simple manner the invention provides for controllable means (23-26) for cutting off the chain fluid supply to the saw device (12) by means of which the pressure line (27) can be cut while the chain fluid pump (20) is running and the chain fluid supplied by the chain fluid pump (20) can simultaneously be fed back into the suction line (29).
