ONE-PIECE CONNECTING ELEMENT OF BARREL Russian patent published in 2018 - IPC B67D1/04 

FIELD: manufacturing technology.

SUBSTANCE: connecting member of the barrel for connecting the metering hose and the hose for supplying the gas to the barrel comprises a closing device with a closing metering orifice and a gas hole. Said connecting element comprises a single-piece solid body in the form of an upper plate with a clamping system for connecting with the possibility of detaching the barrel connecting element from the closing device. Said clamping system comprises two clamping legs protruding from the lower surface of the upper plate. Each of the clamping legs comprises a hinge end connected to two opposite portions of the perimeter of the upper plate and a free end that is opposite to the hinge end and comprises a protrusion towards the free end of the other leg. Two levers protrude from the upper surface of the upper plate and contain a connected end, fixed on the same two opposite portions of the perimeter of the upper plate as the hinge ends of the two clamping legs, and a free end. Pressing the free ends of the two levers towards each other reversibly and elastically sets in motion the two free ends of the clamping legs from each other. Further, the metering tube comprises a cavity providing fluid connection between the inlet end and the outlet end located at the end of the portion downstream of the metering tube. Also, the upstream portion of the metering tube has an outer diameter for fitting into the metering opening of the closing device and projects laterally from the lower surface of the top plate. Said connecting element has a gas tube for fluidly connecting the inlet end and the outlet end. And the downstream portion of the gas tube protrudes transversely from the lower surface of the upper plate parallel to the upstream portion of the metering tube.

EFFECT: group of inventions provides easy detachment and connection to a new barrel.
