Abstract: The invention relates to a drum and to a device (1) therefor, having a system (3) for altering the attack and decay behavior, in particular the note length of the drum (2). The aim of the invention is to provide a device for a drum and a drum having such a device, which can alter the attack and decay behavior quickly and with little effort, and in particular enables setting of the note length and also of the timbre of the drum largely independently of the pitch. This aim is achieved in that the system (3) is fastened to the drum (100, 2) and has a clip (5) on which an adjustable connecting element (6) is arranged, which is designed for a connection to a support arm or to a base support (7).

Abstract: A hydraulic assembly (1), particularly for an electrohydraulic valve control of an internal combustion engine, and a hydraulic valve (2) for forming such an assembly are provided. The assembly includes a hydraulic valve with a valve housing (4) and a valve carrier (3) with a valve receiver (5) in which the valve housing is received. The valve housing has a first circumferential groove (9) and a second circumferential groove (10), with the grooves (9 and 10) being defined respectively by groove walls (13, 15 and 14, 16) and extending on two sides of a hydraulic connection (6) which extends through a peripheral wall of the valve housing (4). A bead (11, 12) formed by a plastic deformation of material of the valve carrier being received in each of the two said grooves (9, 10), so that the groove walls and the beads not only fix the valve housing in the valve receiver by positive engagement but also cooperate with each other to hydraulically seal the valve housing.
