Patent number: 11850459Abstract: 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.Type: GrantFiled: November 7, 2018Date of Patent: December 26, 2023Assignee: HOERBIGER WIEN GMBHInventors: Bernhard Spiegl, Christian Kernbichler, Matthias Kornfeld, Thomas Schragl

Patent number: 11808360Abstract: A scraper ring is provided with a plurality of sealing sections on the radially inner circumferential surface, each including a scraping edge, wherein the sealing sections are spaced axially apart from each other by inner circumferential grooves, with at least one recess provided on the circumference of the scraper ring which extends at least partially from a first axial ring end to a second axial ring end and extends at least partially in a direction different from the axial direction of the scraper ring. At least one drainage opening is provided on the outer circumferential surface of the scraper ring, which is connected to at least one inner circumferential groove for removing scraped oil from the inner circumferential grooves.Type: GrantFiled: September 17, 2019Date of Patent: November 7, 2023Assignee: Hoerbiger Wien GmbHInventors: Marian Janko-Grasslober, Martin Lagler, Andreas Kaufmann

Patent number: 11112810Abstract: 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.Type: GrantFiled: March 19, 2018Date of Patent: September 7, 2021Assignee: Hoerbiger Wien GmbHInventors: Joseph M. Lepley, Steven B. Pirko

Adjusting device for an adjusting piston of a variable clearance space of a reciprocating compressor
Patent number: 10954937Abstract: In order to enable a continuous adjustment of the variable clearance space (1) of a reciprocating compressor (15), a threaded spindle drive with a threaded spindle nut (10) and a threaded spindle (9) is provided as an adjusting device (7), wherein the threaded spindle nut (10) is embodied as a plastic nut (20) with internal thread (24), the plastic nut (20) is arranged with an external thread (23) on an internal thread (22) of a nut carrier (21) of the threaded spindle nut (10), and the thread height (y) of the internal thread (22) of the nut carrier (21) and the thread height (x) of the external thread (25) of the threaded spindle (9) is respectively embodied with 50 to 80% of the radial thickness (d) of the plastic nut (20) and the plastic thickness is at least 15% of the thread pitch (z1) of the internal thread (24) at least in the region of the thread flanks (26) of the internal thread (24) of the plastic nut (20).Type: GrantFiled: October 7, 2014Date of Patent: March 23, 2021Assignee: Hoerbiger Wien GmbHInventors: Bernhard Spiegl, Matthias Kornfeld, Andreas Schloffer -
Patent number: 10753240Abstract: An invention refers to a lubricant injector, a lubrication system and a method for providing lubricant for a piston machine. The lubricant injector is provided with a lubricant inlet conduit and an outlet opening, through which a lubricant is supplied to an inner space to be lubricated of a piston machine. The outlet opening may be selectively opened and closed by means of a needle valve, which is actuated by a magnet coil. The lubricant injector has a flow sensor suitable for determining the quantity of lubricant delivered through the outlet opening.Type: GrantFiled: August 23, 2017Date of Patent: August 25, 2020Assignee: Hoerbiger Wien GmbHInventors: Bernhard Spiegl, Matthias Kornfeld, Jonathan Gauster, Bernhard Fritz
