CamelBak was sold to San Francisco toymaker Kransco in 1996 for $5 million. Bear Stearns Merchant Banking bought it for $210 million in 2004. [3] In 2006, CamelBak expanded into the water bottle business. The company differentiated its bottles by making them taste-free, using bite valves designed to stop leaks while allowing easy sipping.
The volume of the reservoir and the pack carrying it can vary widely depending on the purpose of the hydration pack. Some packs are extremely small and minimalist, designed to add as little weight as possible and remain secure while running or cycling, while others are more suited for backpacking and extended hikes, equipped with much larger bladders.
The bottles are filled upside down, and pressure of the gas in the bottle forces the marble against the washer, sealing in the carbonation. This use of pressure to aid in containment can be seen in other types of check valve. The bottle is pinched into a special shape to provide a chamber into which the marble is pushed to open the bottle.
A check valve, non-return valve, reflux valve, retention valve, foot valve, or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. [ 1 ] Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave.
A valve stem is a self-contained valve that opens to admit gas to a chamber (such as air to inflate a tire), [1] and is then automatically closed and kept sealed by the pressure in the chamber, or a spring, [2] [3] or both, to prevent the gas from escaping.
A tappet or valve lifter is a valve train component which converts rotational motion into linear motion in activating a valve. It is most commonly found in internal combustion engines , where it converts the rotational motion of the camshaft into linear motion of intake and exhaust valves, either directly or indirectly.
Valve seats are often formed by first press-fitting an approximately cylindrical piece of a hardened metal alloy, such as Stellite, into a cast depression in a cylinder head above each eventual valve stem position, [1] and then machining a conical-section surface into the valve seat that will mate with a corresponding conical section of the ...
POL valve on a 45 kg LPG cylinder Male fitting to match POL valve A POL valve (originally for Prest-O-Lite) is a gas connection fitting used on liquefied petroleum gas (LPG) cylinders. The oldest standard for such connections, it was developed by the Prest-O-Lite company, hence the name. [ 1 ]
