  • Patent number: 8613272
    Abstract: Conventional spark-ignited gas engines with a mechanically controlled fuel feed valve have several disadvantages in terms of operation, expensive control, irregular combustion or unstable and unreliable operation, which in turn can lead to operational and mechanical problems. In order to eliminate these disadvantages it is suggested, according to the invention, that a controlled valve is installed in the fuel line upstream of the fuel feed valve so that in the fuel line between fuel feed valve and controlled valve a defined intermediate volume is created and gaseous fuel is fed via the controlled valve into the intermediate volume.

  • Patent number: 7331767
    Abstract: For stepless capacity control of a reciprocating piston compressor, an unloader (2) arranged on a suction valve (1) keeps open said suction valve (1) over a thereby controllable portion of the working cycle of the compressor by means of an unloading piston (4) biased by gas pressure via a control valve (3). The gas pressure biasing the unloading piston (4) is always above the gas pressure required to overcome the maximum possible reverse flow force, whereby a controllable partial discharge of the unloading cylinder (6) is performed in each phase of the working cycle up to the closing of the suction valve (1) by means of the control valve (3), which is designed to switch rapidly. The theoretical discharge time of the entire discharging volume for the partial discharge is preferably maximal nearly equal or even less than twice the duration of the working cycle.

  • Patent number: 7124998
    Abstract: An electromagnetically actuated gas valve (5) for gas engines (4) includes a valve seat (13) that has at least one flow-through opening (14) and a corresponding sealing plate (15), with the sealing plate being movably arranged and guided essentially perpendicularly relative to the valve seat (13), with barrier surfaces (16) and discharge openings (17). The sealing plate (15) is loaded against the valve seat (13) by means of a return spring (25) and can be lifted for the purpose of opening it via a solenoid (21). In order to allow for the secure sealing and easy switchability even in the presence of the effect of the combustion chamber pressure, the sealing plate (15) is arranged on the discharge side of the valve seat (13) and connected by means of a stamp (29), which extends through the valve seat (13), with the anchor plate (28) of the solenoid (21).

  • Patent number: 6726172
    Abstract: A valve for bringing gaseous fuel into the combustion chamber of gas engines is provided with a solenoid valve (8) controlling fuel delivery (7) and an adjoining poppet valve (2), which closes biased by the force of a spring, and which opens in the direction of the combustion chamber through the pressure of in-flowing gas. For the purpose of keeping the poppet valve (2) open, independent from the pressure conditions at its valve head (3), the valve's stem (4) is connected to a step piston (6) whose topside and bottom side are biased by the fuel pressure existing between the solenoid valve (8) and the valve head (3) and whose step area (12) is in communication with the fuel delivery line (7), on one side, and with the space (11) between the step piston (6) and the valve head (3), on the other side, whereby the passageways (15, 15′, 17, 17′) are opened and closed by means of a respective switching member (13, 14, 20) corresponding to the movement of the step piston (6).

  • Patent number: 6390121
    Abstract: A check valve (4) controlled by differential pressure, preferably in form of a disk valve, having a closing element (5) that impacts a valve seat (8) with a force by means of an elastic (resilient) element, preferably a closing spring (6). The closing element (5) is provided with an additional mass (11), which is larger in its amount than the mass of the closing element (5) itself to dampen the closing shock in a manner whereby the closing element (5) does not rebound even once or several times and also to dampen the opening shock of a valve of this type as a matter of course.

  • Patent number: 6318147
    Abstract: A wear monitor suitable in particular for monitoring the wear and tear of rider rings (7) on the pistons (5) of horizontally operating reciprocating compressors presents a sensor (9) that monitors the thickness of the rider ring (7) at least indirectly, is arranged in the area of the rider ring (7) in such a way as to move together with it and can be interrogated without contact via a motionless interrogation unit (16), which communicates with an evaluation unit (18). The sensor (9) preferably presents a passive surface acoustic wave element (23), whose electromagnetic reflection behavior depends on the thickness of the rider ring (7) consequent upon the degree of wear and tear thereof and which communicates with a sensor antenna (19) moving together with it, while the interrogation unit (16) presents a communicating interrogation antenna (20).

  • Patent number: 6230991
    Abstract: A gas valve with electromagnetic actuation, in particular a fuel-injection valve for gas engines, is provided with a sealing member which is actuable by way of the armature of a controllable electromagnet between the or each fuel supply and the or each fuel outlet and with at least one closure spring acting upon the sealing member. In order to provide a gas valve which has—at the same time—a large throughflow cross-section, exact operating and response times as short as possible and a low power consumption and which is also suitable for use in multi-point or ported-gas admission systems and in the case of supercharged engines, in particular in the case of gas engines for commercial vehicles or stationary gas engines, at least one device for compensating the differential pressure acting upon the sealing member is connected to the sealing member.

  • Patent number: 6182943
    Abstract: A gas valve with electromagnetic actuation, in particular for use as a fuel injection valve for gas engines, includes 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 achieve very short switching and response times while at the same time having a large passage cross-section, and thus to render the gas valve suitable also for use in multi-point systems and in supercharged engines, in particular gas engines for commercial vehicles, the gas valve is designed as a flat-seat valve with a plane valve seat (3) and a sealing element (7) with at least one plane sealing surface facing this valve seat.
