Abstract: The invention relates to a valve for controlling a fluid flow, comprising at least one valve housing having at least one inlet and one outlet side, and a valve insert for regulating the fluid flow between the inlet side and the outlet side, which valve is arranged within the valve housing. The valve insert comprises at least one first element, designed as a hollow body, and a second element, wherein the second element is arranged within the first hollow-body-shaped element. Furthermore, the valve insert is arranged within the valve housing in such a way that the first element is axially fixed in the valve housing, and the second element is arranged so as to be rotationally fixed in the valve housing. The first element has at least one opening along the circumference of the first element for passing the fluid flow through and is designed to be rotatable relative to the second element; the second element is designed to be axially movable relative to the first element.

Abstract: A safety-oriented load switching device for the electric switching of an automation component, the device including a first branch circuit and a second branch circuit which extend from a respective supply-side supply connection to a respective load-side load connection, wherein a switching assembly including a parallel circuit of a switching means designed for an opening and a closing of the respective branch circuit and of a resistor means is formed in each branch circuit, and further including at least one measuring point located between the switching assembly and the load connection, and wherein a potential measuring device, which is electrically connected to a reference point and configured for providing a potential-dependent measuring signal, is connected to the measuring point.

Abstract: A tensioning device for the endless drive in a timing system on a motor vehicle, which has a tensioning piston that can move along a path axis in a housing, within which a pressure chamber is located which houses a working medium which brings about a movement of the tensioning piston in the housing and has a valve seat, connected to the exterior of the tensioning piston by an outlet and accommodating a valve body essentially matching the shape of the valve seat. The valve body is tapered along the axial path axis to the outlet, which allows for a large chamber between the valve body and the valve seat. The path that the working medium, on bleeding gas bubbles from the same, takes from the pressure chamber to the outlet is longer, which increases the hydraulic resistance and restricts and limits emptying of working medium from the tensioning piston.
