Hydraulikaggregat, insbesondere für eine schlupfgeregelte Fahrzeugbremsanlage und Verfahren zu dessen Herstellung

摘要

The invention relates to a hydraulic unit (10) with a solenoid valve (16) inserted into a receiving bore (14) of a hydraulic block (12). When there is rigid fastening, the solenoid valve (16) may when under pressure abut a peripheral point of the receiving bore (14) and displaces material of the hydraulic block (12) in the event of alternating stress of the solenoid valve (16)when in operation. The object of the invention is to avoid this disadvantage by using fastening means with a retaining ring (36) peened in the receiving bore (14) and having a collar (40) leaving radial play and formed inwardly into a circulating groove (42) of the solenoid valve (16)
