Abstract

The invention relates to a hydraulic connection sleeve (10) for connecting hydraulic lines (52, 54, 73, 74, 92, 94) for a hydraulic power switch drive (98), comprising at least two Hollow cylindrical base (12,60,77) with annular grooves (14,16,62,64,78,79) encircling its outer cylindrical surface, the annular grooves having sealing rings (18,20,66, 68,80,81), wherein the base body (12,60,77) is made of a material having a first modulus of elasticity. The hydraulic connection sleeves (10) are arranged to be inserted one above the other into the hydraulic lines (52, 54, 73, 74, 92, 94, ), wherein gaps are formed between the substrate (12,60,77) and the hydraulic lines (52,54,73,74,92,94) such that the modulus of elasticity of the first material relative to that of the second material Due to the lower modulus of elasticity when loaded with internal pressure, the matrix (12,60,77) expands more strongly than the hydraulic lines (52,54,73,74,92,94) and is thus technically The resulting gap is closed in the region of the sealing ring. Furthermore, the invention relates to a hydraulic connection ( 50 , 72 , 96 ) having the above-mentioned hydraulic connection sleeve ( 10 ). Additionally, the invention relates to a hydraulic connection plug (100, 120) for closing an open hydraulic line (102).

Description

technical field

[0001] The invention relates to a hydraulic connection sleeve (Hydraulikverbindungsbuchse) for connecting a hydraulic line, for example for a hydraulic power switch drive (Leistungsschalterantrieb), which comprises at least two annular grooves running around its outer cylindrical surface (Mantelflaeche) A hollow cylindrical base body, an annular groove with a sealing ring inserted therein. Furthermore, the invention relates to a hydraulic connection comprising at least one first and a second hydraulic line for a power switch drive with a connection sleeve according to the invention, wherein the hydraulic line is connected by a material having a second modulus of elasticity material, and wherein the connecting sleeves are inserted one above the other into hydraulic lines whose ends abut one another. In addition, the invention relates to a hydraulic plug for closing an open hydraulic line, for example for a hydraulic power switch drive, comprising a hollow cylin...
