Abstract
A vibration dampening system for an air gun charging system includes a rear guide tube and a forward guide tube that are received within opposite ends of an air gun power spring, and a sleeve that fits concentrically over the power spring. The rear guide tube and the sleeve cooperate to reduce the free length of the power spring allowed to vibrate, which reduces vibration and improves firing performance.
Claims20
A charging assembly for an air gun having a compression tube, the charging assembly comprising:
- a piston having a head and a skirt extending from said head along a longitudinal axis, said piston configured for slideably movement within the compression tube from a rearward position to a forward position to compress a gas within the compression tube;
- a power spring having a forward end and a rearward end, with said forward end disposed adjacent said head of said piston, said power spring configured for movement from a compressed position to an uncompressed position to move said piston from said rearward position into said forward position;
- and
- a dampening system for reducing vibration of said power spring in response to said movement of said power spring from said compressed position into said uncompressed position, said dampening system including:
- a rear guide tube at least partially disposed within an inner diameter of said power spring;
- and
- a sleeve defining a bore with said rearward end of said power spring disposed within said bore of said sleeve, wherein said sleeve and said rear guide tube support at least a portion of said power spring therebetween for reducing a length of the power spring which is free to oscillate to limit vibration of the power spring.
A power spring assembly for moving a piston within a compression tube of an air gun, the power spring assembly comprising:
- a power spring extending along a longitudinal axis and defining a hollow core, wherein said power spring is moveable from a compressed position into an uncompressed position when fired;
- and
- a dampening system including:
- a rear guide tube at least partially disposed within said hollow core of said power spring, wherein said rear guide tube is stationary relative to said movement of said power spring;
- and
- a sleeve defining a bore and coupled to said rear guide tube with said rear guide tube disposed within said bore and cooperating with said sleeve to define an annular gap between said rear guide tube and said sleeve, wherein said sleeve is positionally fixed relative to said rear guide tube and stationary with said rear guide tube relative to said movement of said power spring;
- wherein a rearward end of said power spring is disposed within said annular gap with said rear guide tube and said sleeve cooperating to radially support a portion of said power spring to limit radial movement of said power spring along said portion to reduce vibration of said power spring when moved from said compressed position into said uncompressed position.
A dampening system for reducing vibration in a power spring of an air gun when fired, the dampening system comprising:
- a rear guide tube configured for radially supporting an inner diameter of the power spring;
- and
- a sleeve defining a bore and coupled to and at least partially surrounding said rear guide tube with said rear guide tube disposed within said bore, wherein said sleeve is configured for radially constraining an outer diameter of the power spring;
- wherein said sleeve and said rear guide tube are configured for supporting at least a portion of the power spring therebetween for reducing a length of the power spring which is free to oscillate to limit vibration of the power spring when fired.
