Automatic electric actuation of the pumping mechanism of a liquid dispenser apparatus is provided by configuring a hollow tube to cooperate with an electromagnetically driven actuator and further configuring the hollow tube to inter-fit with a stem of a liquid dispensing pump. Actuation of the actuator may, for example, drive the pump stem downwardly to cause a pumping action. Suitable actuators include, for example, solenoids, voice coil actuators and stepping motors.

The container has a side surface portion and a bottom portion. A plunger arranged inside the coil and sliding in a direction along the central axis to move the shaft, and a stator core are provided. The stator core has a plunger accommodating portion and a shaft accommodating portion that accommodates the shaft and attracts the plunger. The plunger accommodating portion has a cylindrical core portion that accommodates the plunger inside, and a flange portion that is provided radially outward at an end of the core portion on the bottom portion side and is welded to the bottom portion of the container. A ring core provided on the opposite side of the shaft accommodating portion to the plunger accommodating portion is provided.

The present invention relates to an aerosol-generating device (1) for generating an aerosol by dispersing an aerosol-forming powder (31) into an airflow. The device comprises a device housing (2) which comprises an airflow passage therethrough and which is configured to receive a capsule (30) that contains the aerosol-forming powder to be discharged into the airflow passage. The device further comprises a magnetic actuator (40) which is configured to generate a movement of the capsule when being received in the device housing for de-agglomerating the aerosol-forming powder within the capsule. The invention further relates to an aerosol-generating system comprising an aerosol-generating device according to the invention and an aerosol-forming powder containing capsule for use with the aerosol-generating device.

An adjustable damping valve device includes a coil carrier with a coil which is wound on an inner sleeve and which has two wire ends which protrude over a winding body. A back iron having a passage for a power supply line of the coil is placed on the coil carrier. The wire ends of the coil are co-located adjacent to one another in an outlet area of the coil carrier, and the back iron has a radial slot which extends from the outer edge of the back iron to the passage and has a width which corresponds at least to the width of the outlet area.

A single solenoid based double actuator device 100 is disclosed having a first actuator 106 configured for linear movement between actuated and dropped positions along an axis of a winding 102 and biased towards dropped position, and a second actuator 120 arranged spaced apart from the first actuator 106 for linear movement between actuated and dropped positions and biased towards dropped position. A pair of magnetic paths, an upper magnetic path 130, and a lower magnetic path 132, is provided at two ends of the actuators such that first actuator, upper plate 130, second actuator 120 and lower plate 132 provide a magnetic path for a magnetic field generated on passing a current through the winding 102. On passing a current exceeding a first current value, through the winding, one of the actuators is actuated, and on the current exceeding a second current value, other actuator is also actuated.

A bistable hoisting solenoid comprising first and second stroke end position and a stroke center position, comprising: a stator, one or more armatures, at least one coil, at least one permanent magnet and a spring system having a first spring which, in the first stroke end position, exerts a force in the direction of the stroke center position on the one or more armatures, and a second spring which, in the second stroke end position, exerts a force in the direction of the stroke center position on the one or more armatures. The one or more armatures, in the event of a loss of current, are held by permanent magnets in both stroke end positions. The first and the second springs have different paths with different lengths and/or exert in the respective stroke end position different sized forces on the one or more armatures and/or have different sized spring rates.

A non-magnetic member, a first magnetic member and a second magnetic member are prepared. The first magnetic member and the second magnetic member are connected to the non-magnetic member. Then, a first bonding portion which bonds the non-magnetic member and the first magnetic member to each other, and a second bonding portion which bonds the non-magnetic member and the second magnetic member to each other are formed. A hot isostatic pressing process is performed to the non-magnetic member, the first magnetic member and the second magnetic member to establish diffusion-bond. Thereafter, the non-magnetic member, the first magnetic member and the second magnetic member are hollowed, and the first bonding portion and the second bonding portion are removed. Thereafter, the non-magnetic member becomes a non-magnetic body, the first magnetic member becomes a first magnetic body, the second magnetic member becomes a second magnetic body and a sleeve is obtained.

An electromagnetic switch for a starting device of an internal combustion engine may include a coil carrier, a coil winding, and a piston. The coil carrier may have a carrier wall which encloses a cavity. The coil winding may have a coil wire wound on a side of the carrier wall facing away from the cavity which provides a magnetic field within the cavity. The piston may be axially adjustable in the cavity. The piston may be disposed in a passive position and may be adjusted axially in a direction of a core. In the passive position, the piston and the core may define an axial gap therebetween in the cavity. The coil wire may have a first winding section and a second winding section wound in opposing directions. At least one winding of the second winding section may axially overlap the axial gap.

A molded coil includes a bobbin, a coil, and an exterior member. The coil is wound around the bobbin, and generates a magnetic force in reaction to power supply. The exterior member covers the coil and the bobbin therewith. Two seams, a first seam and a second seam are provided between the bobbin and the exterior member. A first seal member is disposed on an upstream side of the first seam and between a cover member and the exterior member. A second seal member is disposed on an upstream side of the second scam and between a flange portion of a stator core main body and the exterior member.
