Fruit tree sprayers the use of specific methods and techniques

The [1] of the present invention is a novel and optimization of fruit tree sprayers, with its mobile means for taking liquid from the liquid storage tank pump. As will be described in detail, power sprayer of the invention has a configuration, which allows it to fruit tree sprayers  closely similar to the standard manual sprayer size, look and feel. Therefore, the invention of fruit tree sprayers and before the power sprayer more easily than the hand and less laborious. The disclosure further relates to [2] a new and fluid controller, optimization of the valve and the device used to control, start, stop the flow, also relates to a method for a variety of production and use of these controllers, valves, device. More specifically, the garden hand sprayers  relates to a plurality of controllers, valves and apparatus for in one direction control, start and / or stop the flow, more particularly, relates to a one-way valve actuator can promote the auxiliary components. Fruit tree sprayers further relates to many new and optimized allocation or spray, spray system, power sprayers, hand sprayers, water or other toys, paint sprayers, or a similar liquid or air is returned to the reservoir by means of the device. In particular, distribution device, for example, may include vacuum reservoir can be generated within the drive back to gas valve. In a further embodiment, return air valve may include an actuator, such as for starting valve open bar, buckles, vacuum after generated in the storage groove can be then open the valve and the valve in the open position until the vacuum maintenance has been minimized or eliminated. The disclosed device may further comprise, for the backpack pressure sprayers  of the fluid from the reservoir in the process of moving fluid from the reservoir in the air or in immediately return to the reservoir, so that the air pressure in the reservoir greatly to change back to the ambient air pressure method.
