A gas valve with electromagnetic actuation, in particular for use as a fuel injection valve for gas engines, is provided with a sealing element (7), actuable by way of an armature (12) of a controllable electromagnet (19), between a or each fuel inlet (4) and a or each fuel outlet (24), and at least one closing spring (8) acting on the sealing element (7). In order to obtain an opening cross-section which can be simply and rapidly calibrated and adjusted in a certain range, an element (1, 2, 18) is present for adjusting the distance between the electromagnet (19) and the armature (12).

Gas valve with electromagnetic actuation

A method and apparatus for reducing the loading impact between a sealing element in a suction valve of a piston compressor with a valve stop, wherein the sealing element is forcibly opened using a control device shortly before attaining pressure balance between cylinder and suction chambers of the compressor.

To influence the periodic stroke movement of the closing element of a valve, a control cylinder working on the closing element in the stroke direction is provided, which can be acted upon or released by a control element periodically with pressure medium. The control element is connected in the supply or discharge conduit of the pressure medium and can variably accelerate or slow its pressure formation or release and with it also the stroke movement of the closing element, at last gradually. Thus a partially or completely automatic control of compressor valves, for example, can be made possible in a simple manner.

A valve lifter for compressor valves includes a carrier, and a plurality of fingers secured thereto, the fingers including a retaining element co-operating with the carrier so as to provide a positive fit. At least one retaining element incorporates a positioning element that established its position relative to the carrier, and a fixing element that snaps into position in the installation position on the carrier. It is preferred that the fingers be of long glass fiber reinforced polyamide, which permits a simple and secure connection of the fingers to the carrier that does not settle.
