Hydro compensator to the pressure impact smoothing in the return line of a hydraulic system, and a hydraulic system with such a hydro compensator

摘要

Hydraulic accumulator (40) to the pressure surge smoothing in the return line (30) of a hydraulic system, in particular to a hand held nibbling machine, with a cylinder (41), which is preferably attached to the end caps (42, 43), and with a in the cylinder (41) movable floating piston (50), of the cylinder (41) in a first pressure chamber (51), in which there is a gas, and in a second pressure chamber (52) which divides the to the return line (30) is connected, in which the first pressure chamber (51) to it via a non-return valve which opens in the direction (60) with a gas reservoir (62) is connected, and wherein in an end position of the piston (50) of the first pressure chamber (51) to the return line (30) by only in the end position of the piston (50) effective sealing means (56) is sealed.
