A regulator device for automation technology for actuating a valve device in order to provide regulation of a controlled variable to a setpoint of a setpoint signal. The regulator device has at least one regulator parameter, for example a regulator amplification, on the basis of which the regulation is performed, and the regulator device is designed to detect an oscillation of the controlled variable during the regulation, to classify the detected oscillation into one of a plurality of oscillation classes, and, depending on the oscillation class into which the detected oscillation is classified, to perform a regulator parameter adjustment of the at least one regulator parameter in order to reduce or eliminate the oscillation.

Method for dosing a liquid portion using a dosing apparatus including the steps of pressurizing the liquid reservoir with compressed air by a compressed air source so that the liquid is moved by pressurization in the first channel section and the second channel section, moving the valve member from the closed position to the open position at the beginning of a dosing time, such that the liquid is moved into the third channel section and the fourth channel section and dosed from the dosing tip, moving the valve member from the open position to the closed position at the end of the dosing time, determining an outlet pressure course during the dosing time and/or after the dosing time with the outlet pressure sensor and/or determining an inlet pressure course during the dosing time and/or after the dosing time with the inlet pressure sensor.

A connection device for valves, with a connection body extending along a main axis, which main body has several consecutive valve mounting stands in direction of the main axis, on which valve body valves can be or are mounted. The valve body is provided with at least one row of several consecutive receiving recesses likewise in direction of the main axis, which receiving recesses are transverse to the main axis and leading to a common connection surface of the connection body, which receiving recesses communicate with the connection body channels passing into the connection body and into which suitable connection units can be or are inserted for connecting fluid lines. The inserted use position can be detachably fixed to the connection body by locking means having at least one U-shaped locking bracket. The locking means contain at least two locking channels extending along the main axis in the connection body.

Linear guide having a profiled body extending along an axis of movement and a carriage which is mounted on the profiled body such that it can move linearly along the axis of movement and which has a rolling bearing unit, which bears with at least one rolling element against a guideway. The guideway has two guide rails which are arranged in a row along the axis of movement and which are each positively received on the profiled body in spatial directions aligned transversely to the axis of movement, in which mutually opposite end faces of the two guide rails delimit a joint region and in each case adjacent to the joint region between the respective guide rail and the profiled body a material connection region is formed, which extends at most over 10 percent of a total length of the respective guide rail along the axis of movement.

An actuator device including a magnetic field sensor device and a drive arrangement for performing a drive movement. The drive arrangement has a rotary movement part which includes a first magnetic element and, as part of the drive movement, changes its rotational position relative to the magnetic field sensor device over a rotational position angle range of more than one revolution, and a linear movement part coupled to the rotary movement part, which includes a second magnetic element and performs a linear movement relative to the magnetic field sensor device as part of the drive movement. The magnetic field sensor device is configured to detect the magnetic fields of the first magnetic element and the second magnetic element. The actuator device further includes an evaluation unit which is configured to determine a rotational position of the rotary movement part that is unambiguous with respect to the rotational position angle range.

A valve for controlling fluid flows, including a valve housing in which a control bore extends along a bore axis, in which a first valve member is moveably accommodated along the bore axis between a first open position and a first closed position for a first fluid channel and in which a second valve member is moveably accommodated along the bore axis between a second open position and a second closed position for a second fluid channel and further including a first drive assigned to the first valve member and a second drive assigned to the second valve member, in which a helical compression spring extends along the bore axis from the first valve member to the second valve member and has a central spring section with a central coil pitch which is at least virtually identical to a wire diameter of the compression spring.

Valve module system for supplying compressed air to a compressed air consumer, in which valve modules can be provided with differently configured channel plates in order to enter into fluid communication with fluid channels of a carrier plate, with several connecting channels are formed, which are designed to connect a first valve connection and a second valve connection of a valve assembly to a channel opening of a fluid channel.

A valve control for controlling a solenoid valve, with a controller which has an input interface for receiving a switching signal and an output interface for coupling a solenoid valve and which is designed to process the switching signal and to supply a coil current dependent on the switching signal to the output interface. The controller is designed to regulate the coil current to an pull-in current during a first time period and to regulate the coil current to a holding current which is less than 70 percent of the pull-in current during a subsequent second time period, and to increase the holding current by at least 20 percent for a limited period of time during the second period when a predetermined coil current threshold value is exceeded.

A food vending machine for dispensing food items, including a machine frame, a product display for storing food items, an image processing system for optically detecting a spatial arrangement of food items, a manipulator for handling food items, and a manipulator control for controlling the manipulator depending on the spatial arrangement of the food items. The manipulator control is coupled to the image processing system and the manipulator includes an intermediate storage for the intermediate storage of a selection of food items provided by the manipulator and for the transport of the selection of food items to a packaging unit or to a goods issue area.
