摘要： The invention relates to a tank device (1) for storing a gaseous medium, in particular hydrogen, comprising a valve device (100) and a tank container (200), wherein the valve device (100) comprises a valve housing (102), in which valve housing (102) a pilot valve element (24) that can be moved along a longitudinal axis (101) of the tank container (100) is disposed. The pilot valve element (24) cooperates with a first sealing seat (18) to open and close a passage opening (20) and thus forms a pilot valve (240), wherein the valve device (2) comprises a solenoid coil (32) by means of which solenoid coil (32) the pilot valve element (24) can be moved along the longitudinal axis (101) of the tank device (1). A main valve element (12) is furthermore disposed in the valve housing (102), which main valve element (12) cooperates with a second sealing seat (6) to open and close a passage opening (8) and thus forms a main valve (120), wherein the second sealing seat (6) is configured as a conical shoulder (36) on the valve housing (102). In addition, a permanent magnet (17) is disposed at one end (42) of the pilot valve element (24), which permanent magnet (17) is disposed in the valve device (100) such that a positive pole element (170) of the permanent magnet (17) is disposed in the direction of a housing cover (28) of the valve device (100) and a negative pole element (171) of the permanent magnet (17) is disposed in the direction of the tank container (200), wherein the permanent magnet (17) is disposed in a positive pole region (51) of a permanent magnetic field (52) generated by the solenoid coil (32) when the solenoid coil (32) is energized.

摘要： A fluid compressor system having an electro-magnetic throttle valve (EMTV) that utilizes magnetic forces supplied by an electromagnet to actuate the opening and closing of the valve. The fluid compressor system may include a control system that controls the position of a valve plate of the EMTV, allowing the EMTV to fully or partially actuate to a plurality of intermediate positions depending on a current supplied to the electromagnet by the control system. The control system may control a location of the valve plate with reference to the electromagnet by balancing the forces acting on the valve plate, such as electromagnetic forces supplied by the electromagnet, biasing forces supplied by biasing components, and gravitational forces acting on the valve plate. The EMTV may include a blowdown system configured to release a pressure within the fluid compressor system when the inlet on the EMTV is closed.

摘要： The application of fluidic systems to a variety of consumer devices would typically exploit fluidic structures of a few millimeters to a centimeter or so that are between the common fluidic realms of microfluidics and macrofluidics. For these devices power consumption, portability, batter operation etc. are significant factors in the design and implementation of these fluidic systems. However, the necessary range of fluidic device structures for electromagnetically driven high efficiency pumps, valves, switches, capacitors etc. require development to provide both the required functionality as well as to meet the user expectations for functionality, variability, cost, etc. but also lifetime, reliability, manufacturability etc. of the consumer devices exploiting these fluidic systems.
