The invention relates to a method for operating a piston pump () which is driven by means of a coil () of an electromagnet. A piston () of the piston pump () can be moved in a cylinder () for pumping purposes by means of the electromagnet. A voltage (U) is applied to the coil () during a switch-on period such that a current flows through the coil () and the piston () is accelerated, said voltage being applied by means of an actuation device (). A time curve of an electric state variable (I, U) of the coil () is qualitatively detected, and the curve or a curve derived therefrom is analyzed in order to detect an impact of the piston () against a stop. The invention further relates to an actuation device and a piston pump.

Operating method and actuation device for a piston pump

The invention relates to a method for operating a piston pump, which is driven by means of a coil () of an electromagnet, wherein a piston () of the piston pump can be moved against a restoring force by means of the electromagnet, wherein a voltage (U) is applied to the coil () during a switch-on duration such that a current (I) flows through the coil () and the piston () is accelerated, wherein two different quenching methods are used for the current (I) in the coil ().

Method for operating a piston pump, control device of a piston pump, and piston pump

The invention relates to a piston pump, in particular for injection systems for motorized two-wheeled vehicles and/or for motorized three-wheeled vehicles, having a compression chamber, a piston, an inlet valve, and an outlet valve. A fluid can flow into the compression chamber via the inlet valve, and the fluid can flow out of the compression chamber via the outlet valve. A region in the form of a channel, which is arranged fluidically upstream of the outlet valve, in particular directly upstream of the outlet valve, has a cross-section which is reduced compared to a compression chamber region at a distance from the outlet valve. The invention is characterized in that a piston end face facing the channel has a region which can be immersed into the channel.

The present invention relates to a fuel pump () which comprises a pump housing (), a delivery element () for delivering fuel, a heat-generating actuator () for actuating the delivery element (), a first fuel path () which leads from an inlet () to a delivery space (), and a second fuel path () which leads from the inlet () past the heat-generating actuator () to a first housing opening (), wherein the first housing opening () is arranged above the inlet () in the vertical direction (V). The present invention also relates to a fuel pump arrangement which comprises a fuel pump () according to the invention and a fuel tank () in which the fuel pump () is at least partially and preferably entirely arranged. The present invention also relates to a method for operating a fuel pump ().

Fuel pump with improved delivery properties

A high-pressure fuel pump includes a pump housing with a housing wall and a damping device configured to damp inlet-side pressure pulses by varying a damping volume with an elastically deformable wall. At least one section of the elastically deformable wall is formed from one or more of at least one part of a jacket-like area of the housing wall and at least one part of a sealing support. The section is embodied such that it includes at least one main part configured to vary the damping volume.

High-pressure fuel pump

In a method for generating an internal combustion engine configured to run on both a gas fuel and a liquid fuel, the shutoff valve of the gas injection system is initially closed, the engine is then operated with the liquid fuel, and subsequently all gas injection valves of the gas injection system are opened in a predefined pattern while the shutoff valve is still closed.

An absorption fluid reservoir having a fluid inlet for receiving gases during a charging event and a gas analysis unit for detecting unwanted impurities in the gases prior to being received in the reservoir and a control unit for eliminating the gases having the impurities.

Fluid reservoir having a gas sensor and a filter

The invention relates to a fuel reservoir for gaseous fuel in a vehicle, in particular a sorption reservoir. The fuel reservoir is delimited by at least one wall and includes a sorption material that is contained in its interior. The fuel reservoir has a tank inlet valve containing a shut-off valve and a throttle restriction valve. The restriction of the gaseous fuel takes place inside the fuel reservoir.

Gas absorption reservoir with optimized cooling

Hydrogen or methane gas pressure container having a minimum volume of 1 ma prescribed maximum filling pressure, has a filter through which oxygen, methane respectively, can flow during uptake. The filter has an adsorbent for adsorbing impurities selected from the group consisting of a higher hydrocarbon, ammonia, an odorous substance, hydrogen sulfide and a mixture of two or more of these substances. The pressure container and the filter comprise porous metal organic frameworks as adsorbent.

Pressurised gas container or storage means containing a gas pressurised container with filter means

A vehicle has a fuel system operative to chemically reform a fuel gas, a supply unit for supplying the fuel system with the fuel gas, and a gas reservoir provided with a storage volume for an intermediate storage of the fuel gas, the storage volume having a size that is changeable.

Vehicle with a supply unit

A steer-by-wire steering system comprised of an electronically regulated steering positioner mounted to the steering gear of the front axle or to both front wheels of a vehicle together with an electronic steering regulator and a feedback actuator. A sensor senses the driver's selected direction from the steering wheel. Road feedback can be relayed to the driver through a feedback actuator via the steering wheel. The loss of road feel caused by the absence of the steering column, which normally strongly influences the driver's directional wish, is recreated by the feedback actuator.
