  • Publication number: 20240117825
    Abstract: An assembly for a fluid-filled piston-cylinder unit comprises a main body having an assembly longitudinal axis (24), a valve unit integrated in the main body and having an overflow channel, which valve unit seals the overflow channel when the assembly is moved along the assembly longitudinal axis in a first direction and releases the overflow channel, in dependence on the fluid pressure, when the assembly is moved along the assembly longitudinal axis in a second direction. Furthermore, the assembly comprises an outer seal element that is arranged on the main body so as to be moved along the assembly longitudinal axis, for abutting in a sealing manner against an inner surface of the housing, and at least one undercut element formed on the main body for engaging in an interlocking manner behind a mating element of the piston-cylinder unit.

  • Patent number: 11878972
    Abstract: The present invention is relates to a compound of formula (I), wherein X1, X2 and X3 are, independently of each other, N or CH; with the proviso that at least two of X1, X2 and X3 are N; Y is N or CH; R1 and R2 are independently of each other (iii) a morpholinyl of formula (II) wherein the arrow denotes the bond in formula (I); and wherein R3 and R4 are independently of each other H, C1-C3alkyl optionally substituted with one or two OH, C1-C2fluoroalkyl, C1-C2alkoxy, C1-C2alkoxyC1-C3alkyl, CN, or C(O)O—C1-C2alkyl; or R3 and R4 form together a bivalent residue —R5R6— selected from C1-C3alkylene optionally substituted with 1 to 4 F, —CH2—O—CH2—, —CH2—NH—CH2—, or any of the structures wherein the arrows denote the bonds in formula (II); or (iv) a saturated 6-membered heterocyclic ring Z selected from thiomorpholinyl and piperazinyl, optionally substituted by 1 to 3 R7; wherein R7 is independently at each occurrence C1-C3alkyl optionally substituted with one or two OH, C1-C2fluoroalk
