Abstract
Abstract An evaporator for liquid narcotics, comprising a straight-flow by-pass duct, wherein provision is made for a shutter and a control slide which, when in one of the extreme positions, interacts with the shutter to close gas admission into the bypass duct, and an evaporating chamber. The latter is made as a circular straight-flow channel embracing the by-pass duct and is provided with capillary-structure evaporating elements arranged inside the chamber lengthwise the gas flow lines, and with an effuser provided at the outlet of the chamber concentrically to the shutter so as to establish an annular gap therebetween. The control slide, when in the other extreme position, interacts with the effuser to shut up gas issue from the evaporating chamber.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
148 words
An evaporator for liquid narcotics, comprising: a straightflow by-pass duct; a fixed shutter provided in said by-pass duct at one of the ends thereof; an evaporating chamber having inlet and an outlet openings, said chamber being formed as an annular straight-flow channel encompassing said by-pass duct and communicating with the latter through said openings; evaporating elements having a capillary structure being postioned along said chamber; a generally cylindrically shaped control slide with a tapered portion at the exit end thereof longitudinally movably received in said by-pass duct whereby the by-pass fluid flow passes through said control slide and around said shutter; and an effuser located at the outlet of said chamber, said tapered portion being externally shaped in conformance with the profile of said effuser; said effuser being positioned such that the fluid flows from the by-pass duct and evaporating chamber are directed to converge in correspondent directions.
Claim 2
Dependent Claim
148 words
An evaporator for liquid narcotics, comprising: a straightflow by-pass duct; a fixed shutter provided in said by-pass duct at one of the ends thereof; an evaporating chamber having inlet and an outlet openings, said chamber being formed as an annular straight-flow channel encompassing said by-pass duct and communicating with the latter through said openings; evaporating elements having a capillary structure being postioned along said chamber; a generally cylindrically shaped control slide with a tapered portion at the exit end thereof longitudinally movably received in said by-pass duct whereby the by-pass fluid flow passes through said control slide and around said shutter; and an effuser located at the outlet of said chamber, said tapered portion being externally shaped in conformance with the profile of said effuser; said effuser being positioned such that the fluid flows from the by-pass duct and evaporating chamber are directed to converge in correspondent directions.
Claim 3
Dependent Claim
18 words
An evaporator as claimed in claim 1, said evaporating elements adhering to the surface of said evaporating chamber.
Claim 4
Dependent Claim
22 words
An evaporator as claimed in claim 1, said tapered portion of the control slide being adapted to operatively interact with said effuser.
