A firearm includes a receiver defining a receiver bore and a bolt carrier disposed in the receiver bore. The bolt carrier is moveable relative to the receiver along a longitudinal axis between a firing position and a rearward position. A hand guard is coupled to the receiver and an elongated member is fixed relative to the bolt carrier in the hand guard. A handle assembly is slideably engaged with the elongated member in the hand guard and the handle assembly is moveable toward the receiver to define a charging motion. The bolt carrier presents a first surface and the handle assembly terminates at a terminal surface aligned with the first surface along the longitudinal axis. The terminal surface of the handle assembly abuts the first surface of the bolt carrier when the handle assembly is moved in the charging motion.

A firearm includes a receiver and a bolt carrier disposed in the receiver. The bolt carrier is moveable between a firing position and a rearward position. A rod is fixed relative to the bolt carrier and a hand guard is coupled to the receiver about the rod. A handle assembly is slideably supported by the hand guard and is moveable toward the receiver to define a charging motion and away from the receiver to define a forward assist motion. The handle assembly receives the rod during both of the charging and forward assist motions. An arm is coupled to the base and is moveable between a disengaged position spaced from the rod and an engaged position abutting the rod. When the arm is in the engaged position, the handle assembly is moved to move the rod and the bolt carrier in either of the charging and the forward assist motions.

The present invention provides for a firearm having a receiver defining a bore with the receiver extending along a longitudinal axis. The receiver defines an ejection port transverse to the longitudinal axis with the bore defining an inner surface. The firearm further includes a bolt carrier disposed in the bore and moveable relative to the receiver along the longitudinal axis between a firing position and a rearward position. The firearm also includes a shield longitudinally affixed to the bolt carrier and movable with the bolt carrier as a unit between the firing and rearward positions along the longitudinal axis with the shield blocking the ejection port when in the firing position and the shield sliding along the inner surface away from the ejection port when moving to the rearward position in conjunction with the bolt carrier.

The present invention provides for a firearm including a buttstock defining a first bore extending along a longitudinal axis and a receiver coupled to the buttstock. The receiver defines a second bore extending substantially parallel to the longitudinal axis and in fluid communication with the first bore. The receiver also defines an ejection port transverse to the longitudinal axis. The firearm further includes a bolt carrier disposed in the second bore and movable relative to the receiver along the longitudinal axis between a firing position and a rearward position. The firearm also includes an expulsion device at least partially disposed in the buttstock for flowing air through the first and second bores and out the ejection port as the bolt carrier moves between the firing and rearward positions.

A filling valve apparatus for filling a container with a fluid. The apparatus includes a body portion and a stem. A sleeve is disposed over the stem and is removable from the stem and the body portion when the filling valve apparatus is serviced. A seal is mounted to the bottom of the sleeve. At least one component is movably connected to the sleeve and remains connected to the sleeve when the sleeve is removed from the stem and the body portion during the servicing of the filling valve apparatus. Similarly, a valve assembly, having a housing and a movable plunger is removable from the body portion. At least one member is mechanically connected to one of the housing and plunger for creating a unitary valve assembly that remains intact when the valve assembly is removed from the body portion during servicing of the filling valve apparatus.

A device is provided for interconnecting a support and a connector through a quick release mechanism. The quick release mechanism is normally biased in the locked position and is configured to automatically move from the unlocked position back to the locked position when the connector mates with the support as a user re-connects the unit back to the support. Methods of releasing and re-connecting the unit to the support are also disclosed.

A firearm including a barrel having a breech and a muzzle defining a length of the barrel is disclosed. The firearm includes a hand guard having a first end and a second end with a front sight is attached to at least one of the barrel adjacent the muzzle and the second end of the hand guard. A housing is coupled to the front sight and defines a chamber having a piston disposed therein and movable between static and displaced positions. A receiver is coupled to the first end and a bolt carrier is disposed within the receiver and moveable between firing and rearward positions. A carrier key is attached to the bolt carrier and moves concurrently with the bolt carrier and a rod is permanently affixed to the carrier key and extends to a distal end with the piston engaging the distal end when moving to the displaced position.

摘要:
A filling valve assembly including a support adapted for being operably fixed to a filling machine and through which a liquid is conveyed from the filling machine. The filling valve assembly includes a valve subassembly interchangeably attached to the support, the valve subassembly and support having integrated fluid passages in fluid communication when the valve subassembly is attached to the support. At least a portion of the liquid received by the support from the filling machine is conveyed to the valve subassembly, and at least a portion of the liquid received by the valve subassembly from the support is selectively dispensed from the valve subassembly. The fluid passages of the support and the valve subassembly are connected through fluid openings located in respective interfacing surfaces of the valve subassembly and the support, when the valve subassembly is attached to the support. The filling valve assembly may be a recirculating filling valve assembly.
