| 20100155636 | Pilot Operated Water Valve - A solenoid operated pilot valve utilizes an offset pilot opening and a lever arm to provide a mechanical advantage to multiply the opening force of the solenoid, thereby allowing the solenoid size to be reduced. The lever arm used to position the pilot valving member is mechanically positioned via a solenoid driven plunger in one embodiment, and is positioned by magnetic force alone in an alternative, plungerless embodiment. The lever arm pivots via a fixed fulcrum point, a profiled fulcrum providing continuously variable mechanical advantage, or a stepped fulcrum providing discreet different mechanical advantages as the pilot valving member is moved from its fully closed to its fully opened position. | 06-24-2010 |

| 20100264340 | SOLENOID VALVE - The invention relates to a solenoid valve having a magnet assembly and a valve cartridge comprising a capsule, a valve insert connected to the capsule, an armature that is movably disposed within the capsule. The armature includes a tappet having a locking element and a main sealing element, and a valve body having a main valve seat pressed into the valve insert. A magnetic force generated by the magnet assembly axially moves the armature against the force of a return spring and plunges the main sealing element into the main valve seat in a sealing manner. According to the invention, the valve body is configured as a bonnet-shaped bushing, the open end of which is pressed into the valve insert, and acts as a spring support for the return spring, which is disposed outside of a fluid flow, which is present between the opened main valve seat and at least one radial downstream opening in the valve body configured as a bonnet-shaped bushing. The main valve seat, having a through opening, is disposed inside at a bonnet-shaped end of the valve body configured as a bonnet-shaped bushing. | 10-21-2010 |

| 20140326907 | SOLENOID-CONTROLLED SLIDING INTAKE AND EXHAUST VALVES FOR INTERNAL COMBUSTION ENGINES - A solenoid-operated air inlet or combustion exhaust valve, for a rotary exhaust valve assembly or a sliding plate valve. The rotary exhaust valve has a fixed housing with a cylindrical bore in fluid communication with an air inlet port and/or a combustion gas outlet port, and a cylindrical valve body that rotates within the bore of the fixed housing. The valve body has a gas passage transverse to the axis. The sliding plate valve has a fixed housing with a cylindrical bore in fluid communication with a gas inlet passage and a gas outlet passage, and a plate between the gas inlet passage and the gas outlet passage with an aperture, moving between open and closed positions. An electric linear solenoid reciprocates linearly and operates the sliding plate valve or the rotary valve, directly or through a lever to rotate the rotary valve body, between the open and closed positions. | 11-06-2014 |
| 20150028237 | SOLENOID VALVE - The present invention discloses a solenoid valve, it comprises: a movable core, provided with a flange at a lower end thereof; a driving assembly, in which the flange will abut against a bottom portion thereof and can move up against an upper portion thereof within a chamber of the driving assembly; a piston assembly, a central part of which seals a valve port of the solenoid valve, a periphery of which seals an annular chamber formed between the valve port and a valve body of the solenoid valve, the annular chamber being communicated to the inlet connection pipe, the piston assembly being disposed with a conducting hole at a center thereof, which is sealed by the bottom of the driving assembly; when opening the valve port, the flange of the movable core will first be moved to abut against the upper portion of the driving assembly, and then drive the driving assembly to move up in order to open the conducting hole, wherein since flow of fluid from an upper chamber above the piston assembly into an valve body outlet chamber below the piston assembly through the conducting hole via the valve port is larger than flow of fluid into the upper chamber from an inlet connection pipe of the solenoid valve, an upward force of pressure difference is generated on the piston assembly so that such upward force will enable the piston assembly to move up, thereby opening the valve port. | 01-29-2015 |
