Device for damping of pressure pulsations in a fluid system, especially in a fuel system of an internal combustion engine

摘要

#CMT# #/CMT# The device has housings (38, 40) and an operating chamber (66) that is in communication with a fluid system i.e. fuel system, of an internal combustion engine. A gas volume (58) sealable-closed by membranes (54a, 54b) are provided within the operating chamber, where the device is integrated in housing of a fuel pump. The gas volume is limited by the membranes that are arranged parallel to each other, where edges of the membranes are connected with each other. The operating chamber is sub-divided into two regions by the membranes. #CMT#USE : #/CMT# Device for damping of pressure pulsations in a fluid system i.e. fuel system, of an internal combustion engine (claimed). #CMT#ADVANTAGE : #/CMT# The device is designed in such a manner that the construction and installation of the fuel system is enabled in simple, cost effective and space-saving manner with an increased life span, high stability and reliability, and the membrane is acted upon a mechanical element without any damage so that the plastic deformation is reduced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a device for damping of pressure pulsations in a fluid system of an internal combustion engine. 38, 40 : Housings 43 : Inlet channel 54a, 54b : Membranes 58 : Gas volume 66 : Operating chamber.
