Abstract

The invention concerns a sprayer for a precompression pump comprising the following: a pumping cylinder a piston sliding in the pumping cylinder to define a variable volume pumping chamber an outlet duct extending from the chamber to the nozzle an inlet duct controlled by the valve and extending into the chamber a discharge valve that can be inserted into a discharge valve housing movable with the piston a piston return spring a second spring mounted between the piston and the discharge valve that can exert a spring force in a direction opposite the direction of the piston return spring with the purpose of reducing the corresponding external force that is to be exerted on the piston, whereby the spring force of the second spring is smaller than the predetermined force of the piston return spring.The invention concerns a sprayer for a precompression pump comprising the following: a pumping cylinder a piston sliding in the pumping cylinder to define a variable volume pumping chamber an outlet duct extending from the chamber to the nozzle an inlet duct controlled by the valve and extending into the chamber a discharge valve that can be inserted into a discharge valve housing movable with the piston a piston return spring a second spring mounted between the piston and the discharge valve that can exert a spring force in a direction opposite the direction of the piston return spring with the purpose of reducing the corresponding external force that is to be exerted on the piston, whereby the spring force of the second spring is smaller than the predetermined force of the piston return spring.
