Class Information
Number: 417/364
Name: Pumps > Motor driven > Internal-combustion engine
Description: Apparatus in which the motor comprises a chamber having a movable wall portion (i.e., working member) cooperating therewith to form an alternately expansible and contractable chamber, expansion of said chamber being caused by the burning of a combustible fluid within the chamber, said chamber expansion causing movement of said movable wall portion, the movable wall portion being connected to the pump.
