  • Patent number: 8800823
    Abstract: A valve system for a trigger sprayer including a valve forming an air spring with a portion of the trigger sprayer and being made of a flexible or elastomeric material. The trigger sprayer may include an air-spring valve system wherein the air-spring valve system provides precompression during a pump stroke. The precompression forces developed in the valve system during a pump stroke may originate from an air valve or air pocket trapped between a portion of a valve body and a part of the valve system. For example, a valve may be inserted in a tube retainer which is connected to a valve body of a trigger sprayer. Air trapped in a chamber or space between a portion of the valve and the tube retainer may provide a force against the valve such that a certain force must be applied to the valve before it allows product to be released.
