Description

The spring 29 is pulled by the nut 30.

The inlet nozzle 12 is connected to a liquefied gas receiver (not shown), and the outlet nozzle 13 is connected to a filling head (not shown), the valve of which opens under the influence of an aerosol filter. In order to ensure the cyclical nature of the metering device, the fitting 22 of the pneumatic cylinder 5 is connected via a command device to a compressed air system (not shown).

The dispenser works as follows.

After the dose has been dispensed, the command device stops the supply of compressed air to the pneumatic cylinder 5 through the clamp 22 and to the filling head and connects them to the atmosphere. The clan head filling is closed. Consistently, liquefied gas enters cylinder 1 from the receiver through clamp 12 and valve 14, under pressure of which piston 5 with base 4 and with it rod 7 move downwards. Under the influence of the spring 29, the piston 6 also moves downward until the rod 7 is released to the adjusting bolt 23. The dose is collected.

Subsequently, the command device connects the filling head and the pneumatic cylinder 5 to the compressed air system.

When an aerosol package meets the compressed air head, the compressed air flows through the nozzle 22 into the pneumatic cylinder 5 and moves the upper piston 6, which transfers the movement through the spring 29 to the plugs 7 and the piston 3. The valve 14 closes the inlet nozzle 12 and a dose of liquefied is dispensed gas through the nozzle il3 and aerosol filling head. The dose delivery is stopped when the core 16 of the metering piston 3 closes the output channel 31 in the lid 2, and the piston 6 continues to move forward and compresses the spring by a certain amount a until it reaches the stop 18.

The force from the additional compression of the spring 29 is transmitted through the rod 7 to the piston 3 and serves to ensure the reliable closing of the output channel. The stop 18 establishes a force sufficient for reliable operation; p does not cause deformation of the dosing gauge.

F o ip m u l a and 3 about b | retep and

A batcher for liquefied gases containing a metering. a floating cylinder, inlet and outlet channels - with valves and a pneumatic cylinder with a piston and a rod passed into the dosing cylinder, characterized in that, in order to increase reliability and dosing accuracy, the floating piston is made in the form of a glass with elastic walls and an elastic core on the axis, which is aligned with the output channel, and the pneumatic cylinder stem is spring-loaded and equipped with an adjustable stop.
