Abstract

Acoustic insulator applicable in particular to hydraulic passenger and/or freight elevator pumps consisting of a shaped shell (12) which encloses at least two sides of the motor & pump unit (10) immersed in an oil bath. Said shell is made up of one fluid proof double-walled plastic structure or more forming one or more chambers previously or periodically filled with air. The shell (12) is fixed with preferably plastic clips (18) to the brackets (20) which support the motor & pump unit (10) and is partially immersed in the operating fluid which entirely covers the motor & pump unit. <IMAGE>
