Abstract
A release mechanism is provided for a portable sprayer having a pump unit removably connected to a fluid tank. The release mechanism provides locking for the connection between the tank and the pump unit. Moreover, the release mechanism unlocks the connection between the pump unit and the tank, and operates in conjunction with a pressure relief mechanism to concurrently de-pressurize the tank to ease disconnection from the pump unit. Further, the compass of the pressure relief mechanism also serve to automatically relieve pressure when the pressure in the tank exceeds a predetermined threshold level.
