Amendment 1.10.11. The name of the invention is amended as follows. Title of the invention: Solvent recovery device The scope of the claims for utility model registration and the brief description of the drawings are amended as follows.

[Scope of Claim for Utility Model Registration] An adsorption tower that houses an adsorption filter and has a discharge port that can be opened and closed, a processing gas supply line that supplies a solvent-containing processing gas to the adsorption tower, and a heating medium for desorption to the adsorption tower. a heating medium supply line, a condensation section that condenses the solvent desorbed by the heating medium, a separation section that separates the condensed solvent, and a recycle line that joins the gas phase of the separation section to the processing gas supply line. In the solvent recovery device, the line between the condensation section and the separation section, the separation section, or the recycling line is provided with a pressure adjustment section whose capacity is variable in response to pressure fluctuations in the line. Solvent recovery equipment.
