摘要： A device is designed to be coupled to a fluid supply at a first inlet, to a fluid exhaust path at an outlet, and to an additive source at a second inlet. An inlet stream of working fluid is mixed with the additive in a mixing chamber and an outlet stream of the mixed fluid exhausts from the device. The device uses a hydraulic pump employing a valve mechanism that cycles and ports the flow of fluid through the device and allows for the mixing of the working fluid in the mixing chamber. The valve mechanism is spring actuated by a linkage mechanism employing a push-pull linkages tensioned by a spring. The mixing action allows a specific quantity of additive to mix with the working fluid in the mixing chamber of the device. Thus, the outlet stream provides a mixture of a predetermined concentration of whatever additive is used.

摘要： A hand holdable pump spray apparatus is disclosed where the pump mechanism is in the hand holdable wand (14) rather than in a spaced apart liquid container. The wand (14) may be held with one handle (54) is extended with other hand. This creates a pressure differential which allows liquid to flow from the container (10), passed a check valve (84) and into the wand (14). After filling, a biased spring provides a force against the liquid creating a higher pressure in the wand (14) than ambient pressure. This closes the check valve (84). When an operator depresses an actuator (68), another valve (88) opens allowing the liquid in the wand (14) to be ejected through a nozzle (66).
