Abstract:
A clamping element for a fuel injector is provided that is insertable into a mounting hole of a cylinder head of an internal combustion engine, and that directly injects fuel into a combustion chamber of the internal combustion engine has a first step ring. This at least partially surrounds the fuel injector and has a valve pressure surface that may rest on the fuel injector. The first step ring has at least one circumferential slope surface on its side facing away from the valve pressure surface, which engages with a corresponding circumferential slope surface of a second step ring, which has a counterpressure surface. The slope surfaces are arranged so that the first step ring and the second step ring are pressed axially apart when they are rotated relatively to one another.
Abstract:
The invention relates to a pH-dependent controlled release pharmaceutical composition, comprising at least one pharmaceutical active ingredient, with the exception of opioids, wherein the core is coated at least by one coating layer, controlling the release of the pharmaceutical composition, wherein the coating layer comprises a polymer mixture of i) 40-95% by weight, based on dry weight of the polymer mixture, of at least one water insoluble essentially neutral vinyl polymer or copolymer, and ii) 5-60% by weight, based on dry weight of the polymer mixture, of at least one anionic polymer or copolymer, which is insoluble in a buffered medium below pH 4.0 and soluble at least in the range from pH 7.0 to pH 8.0, characterized in that the coating layer further comprises 110 to 250% by weight of a non-porous inert lubricant, 1 to 35% by weight of at least one neutral cellulosic compound and 1 to 25% by weight of at least one emulsifier, each calculated on dry weight of the polymer mixture.
Abstract:
The hold-down device for a fuel injection device has a design which is simple in particular, which nonetheless enables a fuel injector (1) to be held down very effectively. The fuel injection device includes at least one fuel injector (1), a receptacle bore for the fuel injector (1) and a connecting fitting (6) of a fuel distributor line (4), the hold-down device (10) being clamped between a shoulder (12) of the fuel injector (1) and an end surface (14) of the connecting fitting (6). The hold-down device (10) has a base element (11) in the shape of a partial ring, from which an axially flexible hold-down clip (13) extends in a bent-away fashion, the clip having at least two webs (21), two oblique segments (22), and two contact segments (23). The fuel injector (1) is suitable in particular for use in fuel injection systems of mixture-compressing, externally ignited internal combustion engines.

Abstract:
The fuel injection device provides a particularly effective sound-decoupling construction. The fuel injection device has at least one fuel injection valve, a receptacle bore for the fuel injection valve in a cylinder head, and a fuel distributor line having a fitting in which the fuel injection valve is placed in partially overlapping fashion. A connecting element is situated in the receptacle bore such that the fuel injection valve is held in the connecting element such that the fuel injection valve and the connecting element are held so that they do not contact any surfaces or walls of the receptacle bore of the cylinder head that do not run axially parallel to the fuel injection valve. For this purpose, the connecting element is attached immediately on the fitting of the fuel distributor line.The fuel injection valve is particularly well-suited for use in fuel injection systems of mixture-compressing externally ignited internal combustion engines.

Abstract:
The invention relates to a main housing element for a multi-part housing of an electrical device. The main housing element consists of a frame element and at least one connector element integrated in the frame element and produced in one piece with the frame element. The connecting region between the at least one connector element and the frame element is configured as a predetermined breaking point. In the course of assembly of the main housing element a mechanical separation of the connector element from the frame element takes place, whereby the connector element and the frame element are uncoupled.
