  • Patent number: 9816849
    Abstract: A fluid dispensing apparatus includes an actuator body with an actuator and a valve stem coupled for movement with the actuator, and a fluid body having a fluid chamber capable of fluid communication with an outlet. The valve stem is adapted to extend from the actuator body into the fluid chamber for dispensing fluid from the fluid chamber through the outlet. A quick connect member is provided to selectively fully engage and disengage a first coupling element on the actuator body with a second coupling element on the fluid body, to connect and disconnect the actuator body and the fluid body with respect to each other. The quick connect member advantageously connects or disconnects these bodies without requiring disassembly or dismounting of the bodies from other elements associated with the fluid dispensing apparatus, with a simple manual movement such as a sliding linear continuous movement.
