Abstract
A gas spring for use in a gas suspension system. The gas spring includes a gas inlet port configured to receive compressed gas and a gas inlet chamber connected via an inlet conduit to the gas inlet port and via an opening to an internal volume of the gas spring. The inlet conduit is connected to the gas inlet chamber at a position offset from a central axis of the gas inlet chamber such that an angle between a longitudinal axis of the gas inlet port and a surface of an interior wall of the gas inlet chamber opposing the gas inlet port is acute.
Claims18
A gas spring for use in a gas suspension system, the gas spring comprising:
- a gas inlet port configured to receive compressed gas;
- a gas inlet chamber;
- an inlet conduit connecting the gas inlet chamber to the gas inlet port;
- and
- an opening connecting the gas inlet chamber to an internal volume of the gas spring;
- wherein the inlet conduit is connected to the gas inlet chamber at a position such that a longitudinal axis of the inlet conduit is offset from a central axis of the gas inlet chamber and such that an angle between the longitudinal axis of the inlet conduit and a surface of an interior wall of the gas inlet chamber facing the inlet conduit is non-perpendicular and such that gas entering the gas inlet chamber from the inlet conduit impinges the surface at the non-perpendicular angle,
- wherein the gas inlet port and the gas inlet chamber share a cross-sectional plane, the cross-sectional plane normal to the central axis of the gas inlet chamber.
