摘要： A circuit for controlling current flow to an associated inductive load is provided. The circuit includes a switching element having an open state and a closed state that intermittently connects an associated power supply to the inductive load when the switching element is in the closed state, a switch driver that generates a switch drive signal provided to a control element of the switch that controls the state of the switch to be the open state or the close state based on a desired load current set point and a feedback signal, a current sensor that measures a current flowing through the switching element and the load and generates a sensed current signal, and a summing circuit that adds a representation of the sensed current signal and a supplemental signal comprising a representation of the switch drive signal to generate the feedback signal.

摘要： To produce sealing plates (1) consisting of a plurality of sealing rings (3) connected by radial webs (2) by injection molding, wall-type guide elements (5) are arranged obliquely to the direction of flow in the mold channel (6) which is therefore initially largely constricted in the region of weld lines (15) formed by the convergence of the fronts of the divided plastic melt streams, said guide elements being moved out of the mold channel (6) during the further filling of same so that the strength is significantly improved in the region of the weld lines (15).

摘要： Due to increasingly strict requirements and regulations, it is becoming more and more important for piston compressors to reduce the amount of leakage of operating medium through the seal of the piston rod. Conventional seals comprising packing rings and/or packing ring combinations always have a certain amount of leakage, both during operation and when at standstill, which is why they are not usable for certain applications, or the complexity involved in such a seal increases considerably. A further problem involving the seals of piston rods relates to transverse movements by piston rods during which the sealing action of the seal must be maintained. Proposed is, therefore, a sealing arrangement according to the principle of a sealing medium barrier providing that the sealing elements 8, 9 are arranged in radial direction at a distance relative to the radial end of the recess 10 that receives the sealing elements 8, 9.
摘要翻译：由于越来越严格的要求和规定，活塞式压缩机通过活塞杆的密封件减少操作介质的泄漏量变得越来越重要。包括填料环和/或填料环组合在内的常规密封件在操作期间和在静止时总是具有一定量的泄漏，这就是为什么它们不能用于某些应用，或者这种密封件涉及的复杂性显着增加。涉及活塞杆密封件的另一个问题涉及活塞杆的横向运动，在此期间必须保持密封件的密封作用。因此，提出根据密封介质阻挡层的原理的密封装置，条件是密封元件8,9相对于容纳密封元件8,9的凹部10的径向端部沿径向方向布置一定距离。

摘要： Conventional wiper arrangements with cut rings suffer from unavoidable leakage and, in particular in an embodiment as metallic wiper ring with a sharp wiping edge, scratch on the surface of the piston rod which can be damaged in this manner. In order to eliminate these problems, a wiper arrangement with a wiper ring 2 which is split in the circumferential direction and an L-shaped cover ring 3 which is split in the circumferential direction is proposed, wherein the splitting points 16, 15 of the cover ring 3 and the wiper ring 2 are arranged offset to each other in the circumferential direction, and the wiper ring 2 is arranged abutting axially as well as radially in the recess 4 of the L-shaped cover ring 3, and the radially inner circumferential surfaces 6, 7 of the wiper ring 2 and the cover ring 3 form a common radially inner wiping surface 10.
