Abstract
A system releases spray fluid in different mass flow rates. The system includes an actuator having a first area and a second area, a stem connected to the actuator and having a first orifice and a second orifice, a gasket covering the first orifice and the second orifice in a non-actuated position, and a biased member biasing the stem to the non-actuated position. When the first area of the actuator is pressed, the stem moves a first distance relative to the gasket to uncover the second orifice and compressing the biased member to spray fluid with a first mass flow rate. When the second area of the actuator is pressed, the stem moves a second distance relative to the gasket to uncover the first orifice and the second orifice to spray fluid with a second mass flow rate greater than the first mass flow rate.
