Abstract
An actuator button assembly for a finger-operated fluid dispenser including a compression chamber located in the actuator button, a piston slidably located in the compression chamber, an insert having an orifice therein fitted adjacent to the compression chamber, resilient means for biasing the piston toward the insert, and a cylindrical pin extending from the piston for contacting and sealing the orifice located in the insert.
Claims10
A pressure operated actuator button assembly for a finger operated fluid dispenser comprising:
- a. an actuator button having:
- i. a generally cylindrical compression chamber means having two ends;
- ii. inlet channel means communicating with said compression chamber means for conveying pressurized fluids to be dispensed to said compression chamber means;
- b. an orifice located in one of said ends of said compression chamber means through which fluids exit from said compression chamber means to the atmosphere;
- c. piston means slidably received in said compression chamber means, said piston means having pin means for sealing said orifice and scaling collar means slidably received in said compression chamber means for containing fluids to be dispensed in said compression chamber means between said scaling collar means and said orifice;
- and
- d. resilient means for biasing said piston means towards said orifice and for allowing said piston means and said pin means to slide away from said end of said compression chamber means containing said orifice when fluids under sufficient pressure are conveyed to said compression chamber means through said inlet means to allow fluids to be dispensed through said orifice.
