DEFINITION
Classification: 417/243
(under the class definition) Apparatus in which the pumped fluid is first acted upon by one pump or pumping member and subsequently acted upon by a second pump or pumping member and provided with heat exchange apparatus interposed between the pumps or pumping members to dissipate heat from the pump fluid generated by the pumping operation.
(1) Note. To be classified under this definition there must be claimed some structure peculiarly adapted to cooling or heat exchange such as fins, cooling fan, etc., or a specific structural relationship of the intercooler to the pump. A mere conduit between stages in which cooling might incidentally occur would be excluded. The mere claiming of an "intercooler" or "cooler" is not sufficient to cause classification under this definition.
