Patent ID: 7308910

Claim:
A device for damping pressure surges in a fluid, comprising: a housing having a longitudinal axis and a connecting piece; a spring-type accumulator in said housing; a first piston displaceable in said housing against pretensioning forces of said accumulator; a second piston displaceable in said connecting piece along said longitudinal axis, said first and second pistons being mechanically uncoupled, said accumulator biasing said first piston such that said first piston exerts a compressive force on said second piston and said pistons are in constant contact with one another in all positions of said pistons and extending axially along an entire length thereof between oppositely axially facing surfaces of said first piston and said housing, said first and second pistons being in a non-overlapping arrangement and extending in opposite directions from abutting surfaces thereof; and an anti-loss device is attached to said connecting piece at a side of said second piston remote from said first piston.
