The invention relates to a small-sized sprayer with electric pump for processing fruit trees, berry bushes, vegetables and ornamental plants liquid solution for chemical protection against pests and diseases, foliar feeding of plants, economical watering with a wide dispersion in the conditions of the farms.
Known used in private gardens and even farmers portable sprayers, consisting of a reservoir for the working fluid from the filler neck filter, hand pump and outlet tube hose (see SU # 246207 IPC AM 7/00).
The spray liquid flows in these sprayers are driven by compressed air from a weak hand pump. The air pressure in the tank is checked with a gauge and in these sprayers do not need regulators of fluid pressure.
The pressure fluid used in agricultural machinery sprayers with mechanical and electrical pumps. Working bodies of these sprayers consist of tanks, pumps, filters, pressure regulators, nozzles, spraying systems and filling devices. (See Tutorial Wemhoener, Ipharmacy "Agricultural machines". Moscow, Colossus, 2004 str...218. ).
In the engine sprayers set, piston, centrifugal, gear, diaphragm, ro is iMovie and rotary pumps. The main characteristics of the pump flow (l/min) and fluid pressure (MPa). Vibrating pumps in machinery chemical plant protection is not applied as thin and do not provide high performance in large farms.
However, in gardening and farming the use of cheap and small sprayers on the basis of the vibration of the pumps will allow a significant increase productivity and eliminate manual work by pumping air into pnevmopistoleta with a working tank liquid not more than 10 litres.
Pressure regulators are used to regulate and maintain the operating pressure in pressure communication sprayer. Known pressure regulators (see  str...219, .VI.2) consists of a water chamber that receives fluid from the pump through pipe communication and which contains a pressure reducing and pressure relief valves. Spring pressed valves to seat drain holes. From the pump the liquid flows through the filter into the working chamber and out through the opening to the spray device. As soon as the fluid pressure in the working chamber exceeds a specified maximum, the pressure reducing valve opens and the excess fluid is discharged into the tank through pipe communication. Pressure reducing valve set at the desired pressure to the e screw. Safety valve to regulate the maximum pressure and sealed. The safety valve is triggered when a faulty pressure reducing valve. The pressure regulator is equipped with a pressure gauge to control the working fluid pressure.
Known pressure regulators applicable to machinery sprayers and not applicable as the pressure regulators for vibrating pumps operating in limbo in terms of irrigation. In terms of irrigation also there is no need for pressure regulators for vibrating pumps running on pure water in a stable mode in the absence of sprays, sometimes Zabarauskas when spraying and creating in the moment clogging the sharp increase in the discharge pressure in the pump. Vibration pump type "Baby", "Brook", "Neptune", "Strumok", available for irrigation in the Russian Federation, Belarus, Ukraine, relates to pumps low (0,4...0,6 MPa) pressure, and it is very sensitive to overloading, however, provides for the vortex sprayer sustainable and long pressure jet spray of liquid.
The technical result, which directed the present invention is the creation of a simplified, compact design of the pressure regulator of the pressure fluid from suspended above the tank vibration pump with sbro the om pressurized fluid at a pressure directly into the tank.

Piece body 1 made of non-ferrous metals: brass or bronze. The thrust screw 10 is locked by the screw 15. For the implementation of the liquid when the clogging of nozzle (not shown) between the stop 8 and the thrust screw 10 expose the gap "and"sufficient to discharge the liquid solution. When the overload pressure force "P" overcomes the force of the spring 11 and resets the liquid in the tank in the form of a portable tank or barrel when the floating sprayer
where P is the pressure force in the city;
d - hole diameter 5 cm;
ρ - specific pressure in g/cm2;
P1the force of the spring,
Thus, a drain valve 6 pressure regulator is a system of protection of the motor in case of overload, such as when paper jams in the system fluid supply and high voltage.
