    摘要: An electromagnetic fuel injector comprises a body having a fuel inlet and a fuel outlet and a base comprising a valve seat sealably connected to the body. A disk-shaped armature disposed at the fuel outlet for controlling the flow of fuel has an upper surface and a lower surface that comprises a sealing interface with the valve seat. A ring-shaped flexural element comprising a plurality of spaced flexural legs is in contact with the injector body and the upper surface of the armature and provides a spring bias between the body and armature upper surface. When the injector is closed, spring bias between the body and armature upper surface maintains the armature in a sealing position with the valve seat, and when the injector is open, increased spring bias between the body and armature upper surface impels the armature to return to a sealing position with the valve seat.

    摘要: A method for locating an injector ball valve guide in alignment with a valve seat mounted in a common recess of an injector valve body. The valve guide is a disk that has a central opening which guides a valve ball of an associated valve member. During assembly, the guide disk is aligned with the valve seat by a locating tool having an oversized ball on a load rod. The oversized ball is fitted closely within the central opening of the guide and is seated on the ball seat to align the seat and opening. The valve seat and guide disk are then locked in the recess by crimping edges of the recess against the valve seat. The locating tool is removed and assembly of the remaining injector components is completed. The method simplifies alignment of the seat and guide components. In a variation of the method, the guide is aligned with and fixed to the valve seat with the oversized ball in place to form an aligned subassembly for subsequent installation into a fuel injector.

    摘要: An attachment element for a body which can be inserted through a bore in a wall. The attachment, element fixes the body in place by being locked in place. The attachment element is structured to be resilient and can be deformed in such a way, by pressing on suitable points, that the catch hooks are unlocked when pressure is exerted. In this way, the attachment element can be easily released again, without tools and in simple manner.

    摘要: A catalyst for decreasing the content of nitrogen oxides in flue gases. The catalyst contains at least one of the metals titanium, zirconium, vanadium, tungsten, molybdenum, or cerium in the form of one or more of their oxides combined with a silicate with a three-layer structure (three-layer silicate) comprising acid-activated pyrophyllite. The crystalline layer structure of the acid-activated pyrophyllite is essentially retained, while being not yet X-ray amorphous. The acid activation increases the BET surface area at least 15% and preferably at least 50% in terms of the BET surface area of the pyrophyllite before acid activation. The atomic ratio of the silicon in the acid-activated pyrophyllite to the metal in the oxide is from 0.2 and 50 and preferably from 0.4 to 25.
