US12736299 - Valve assembly for a projectile launching system
The patent describes a valve assembly for a projectile launching system that includes a housing with an expansion chamber and a movable bolt that can transition between three positions to control fluid coupling and sealing. This assembly features a longitudinal through hole, a radially disposed through hole, and a sealing member to manage the flow of pressurized gas.
Claim 1
1 . A valve assembly, comprising: a housing assembly; an expansion chamber configured to receive a pressurized gas source and positioned inside of the housing assembly; a bolt with a first bolt end and a second bolt end, wherein the bolt is slidably positioned in at least part of the expansion chamber and movable from a first position to a second position relative to the housing assembly, the bolt also movable from the second position to a third position relative to the housing assembly, the bolt having a longitudinal through hole from the first bolt end to the second bolt end; at least one radially disposed through hole extending from a radially outer bolt surface to the longitudinal through hole, wherein the translation of the bolt relative to the housing assembly from the first position to the second position fluidly couples the expansion chamber with the at least one radially disposed through hole, wherein the translation of the bolt relative to the housing assembly from the second position to the third position fluidly seals the expansion chamber from the at least one radially disposed through hole; an orifice configured to allow a passage of a gas from the expansion chamber to a first bolt surface; a stem coupled to the housing assembly, wherein the stem is configured to at least partially sit within the longitudinal through hole of the bolt when the bolt is in the first position; and a sealing member, wherein the sealing member is configured to seal the expansion chamber from the orifice, the sealing member having a first sealing member position sealing the orifice from the expansion chamber, the sealing member having a second sealing member position fluidly coupling the orifice and the expansion chamber. a housing assembly; an expansion chamber configured to receive a pressurized gas source and positioned inside of the housing assembly; a bolt with a first bolt end and a second bolt end, wherein the bolt is slidably positioned in at least part of the expansion chamber and movable from a first position to a second position relative to the housing assembly, the bolt also movable from the second position to a third position relative to the housing assembly, the bolt having a longitudinal through hole from the first bolt end to the second bolt end; at least one radially disposed through hole extending from a radially outer bolt surface to the longitudinal through hole, wherein the translation of the bolt relative to the housing assembly from the first position to the second position fluidly couples the expansion chamber with the at least one radially disposed through hole, wherein the translation of the bolt relative to the housing assembly from the second position to the third position fluidly seals the expansion chamber from the at least one radially disposed through hole; an orifice configured to allow a passage of a gas from the expansion chamber to a first bolt surface; a stem coupled to the housing assembly, wherein the stem is configured to at least partially sit within the longitudinal through hole of the bolt when the bolt is in the first position; and a sealing member, wherein the sealing member is configured to seal the expansion chamber from the orifice, the sealing member having a first sealing member position sealing the orifice from the expansion chamber, the sealing member having a second sealing member position fluidly coupling the orifice and the expansion chamber.
