Various aspects of the invention are directed to a triggering device for a quickly triggering extinguishing system for explosion suppression. In some embodiments of the present disclosure, the triggering device may include a pawl body having a pawl flank, a catch, at least one electromagnet to transmit an electromagnetic field, and a sliding pin. The sliding pin triggers an extinguishing system for explosion suppression by movement from a blocking position into a release position. In the blocking position, the sliding pin is pushed against the pawl flank of the pawl body by means of the catch and is held in the blocking position by said pawl flank. The pawl body releases the engagement of the catch and the pawl flank, and thereby releases the sliding pin, in response to the at least one electromagnet exerting the electromagnetic field on the pawl body.

Triggering device of an extinguishing system

High temperatures of the sealing medium occur in a hydraulic sealing medium barrier for sealing a piston rod of a piston compressor, and there is the risk of soil and abrasion being deposited there and interfering with the function of the seal. To prevent this, a sealing configuration () which is provided for circulating sealing medium through an outlet line () for sealing medium which is connected to the recess (), and a circulating device () is provided, with which the sealing medium is circulated through the recess () while maintaining the pressure (p) of the sealing medium through the inlet and the outlet line ().

Sealing configuration for sealing a reciprocating piston rod of a piston compressor

In a reciprocating piston compressor with delivery rate control, the electromagnetic actuating device () of the valve lifter () has a separate positioning drive () for adjusting the working stroke range of the magnetic actuator () used, whereby this can be chosen to be small and highly dynamic and only low power losses occur.

Reciprocating piston compressor with delivery rate control

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 elementsare arranged in radial direction at a distance relative to the radial end of the recessthat receives the sealing elements
