ABSTRACT OF THE DISCLOSURE An improved fluid spray pump is disclosed for spraying a fluid from a fluid container through a terminal orifice comprising a housing having an internal cylinder with a first and a second end. A collar with an internal collar aperture is mounted adjacent the first end of the housing internal cylinder. One way valve means connects the fluid container to the housing internal orifice by conventional means. A pump barrel is slideably received in the internal collar aperture and includes a barrel internal bore communi- cating with a terminal orifice in the pump barrel. A piston comprising a piston stem is received in the barrel internal bore of the piston barrel and with a piston head received within the housing internal cylinder. Channel are provided along the piston stem for communicating the housing internal cylinder with the terminal orifice. An annular seal is slidably mounted relative to the piston and the pump barrel for sealing the channel means when the annular seal aubts a shoulder formed between the piston head and the piston stem. The annular seal enables fluid flow through the channel means to the terminal orifice when the annular seal is disposed from the piston shoulder by movement if the pump barrel toward the second end of the housing internal cylin- der. A trigger slides the pump barrel toward the second end of the housing internal cylinder against bias means such as a spring coacting between the piston and the housing internal cylinder. The foregoing abstract is merely a resume of the general application, is not a complete discussion of all principles of operation or application, and is not to be construed as a limitation on the scope of the claimed subject matter.
