Abstract
The present disclosure is an accumulator that has an oil chamber, a first piston separating a first gas chamber from the oil chamber, a second piston separating a second gas chamber from the oil chamber, and a compressible member positioned between the second piston and a stop. The compressible member is configured to dampen motion of the second piston towards the stop.
Claims20
An accumulator, comprising:
- an oil chamber;
- a first piston separating a first gas chamber from the oil chamber;
- a second piston separating a second gas chamber from the oil chamber;
- and
- a compressible member positioned between the second piston and a stop;
- wherein, the compressible member is configured to dampen motion of the second piston towards the stop.
3 more elements
An accumulator, comprising:
- a housing defining a gas chamber and an oil chamber;
- a piston positioned within the gas chamber and configured to selectively slide therein;
- and
- a compressible member coupled to the piston and configured to contact a stop;
- wherein, as the piston approaches the stop, the compressible member dampens the movement of the piston.
2 more elements
A method of assembling an accumulator, comprising:
- coupling a compressible member to a piston;
- and
- positioning the piston in a housing to selectively slide along an accumulator axis such that the compressible member is positioned between the piston and a stop, the piston fluidly separating an oil chamber from a gas chamber;
- wherein the compressible member is configured to selectively dampen the motion of the piston towards the stop.
