Abstract
A manually operable spray pump with a double-action pump and a detachable fluid reservoir. A pump cylinder has valves at each end to admit air into one of two pump chambers formed by a piston and means to simultaneously force air from the other chamber down a shaft and out over a fluid discharge port, thereby pulling fluid from the reservoir and spraying it from the device.
