| 251129170 | Having diaphragm between coil and opening controlled | 7 |
| 20080203344 | DIAPHRAGM CARBURETOR WITH ELECTROMAGNETIC ACTUATOR - A diaphragm carburettor comprises a diaphragm dosager ( | 08-28-2008 |
| 20090212248 | Solenoid-actuated diaphragm valve - A solenoid-actuated diaphragm valve achieves minimal dead volume, tolerance of high pressures, prolonged diaphragm life, and energy conservation using a three-sector multi-seal diaphragm combined with a three-component plunger, which automatically switches from bilateral to unilateral circumferential diaphragm restraint between the closed and open positions. | 08-27-2009 |
| 20100019181 | Apparatus and method for controlling fluid flow - An actuator base, bobbin, and pole piece form a pocket for an armature that a flexible membrane encloses to form an armature chamber filled with an incompressible fluid. The membrane protects the armature from exposure to corrosive fluids flowing in a conduit. Conduit flow can be stopped by driving the membrane against a valve seat. Pressure from the controlled fluid in the conduit is transmitted through the membrane to the fluid within the armature chamber so that the armature does not need to counteract force applied to the membrane by the conduit fluid's pressure. | 01-28-2010 |
| 20110042598 | Solenoid-actuated diaphragm valve - A solenoid-actuated diaphragm valve achieves minimal dead volume, tolerance of high pressures, prolonged diaphragm life, and energy conservation using a three-sector diaphragm in concert with a constraining plate which confines vertical displacement to the central sectors of the diaphragm. | 02-24-2011 |
| 20130020516 | DUAL DIAPHRAGM VALVE - A dual diaphragm valve ( | 01-24-2013 |
| 20130256574 | MAGNETIC-ANISOTROPIC PLASTICALLY DEFORMED BODY, METHOD FOR PRODUCING THE SAME, AND ELECTROMAGNETIC APPARATUS USING THE SAME - A material containing a soft magnetic substance is subjected to a plastic deformation such as a roll processing to obtain a rod-shaped body. Then, the rod-shaped body or a shaped body obtained by processing the rod-shaped body into a shape other than a flat plate shape is subjected to a heat treatment in the presence of a magnetic field. The rod-shaped body or the shaped body is made magnetic-anisotropic by the heat treatment thereby to obtain a magnetic-anisotropic plastically deformed body. | 10-03-2013 |
| 20130313456 | SWITCHABLE PRESSURE LIMITING VALVE - A switchable pressure limiting valve with an electromagnet ( | 11-28-2013 |
