Abstract:
A solenoid valve is provided with a valve main body having a valve chamber communicating with an inlet port and a first outlet port, a valve body arranged within the valve chamber, a valve holder retaining the valve body, a coil spring energizing the valve holder, a pipe member having a second outlet port communicating with the valve chamber, a suction element surrounding the pipe member, a coil bobbin winding an electromagnetic coil, and a mold cover surrounding a whole of the coil bobbin, integrated with the valve main body, and defining the valve chamber. The valve holder has a tube body facing to the suction element, and a small tube portion formed smaller in diameter than the tube body, pierced a fluid insertion hole in an intermediate portion, and having a retention portion retaining the valve body in an inner side of a leading end.
Abstract:
For the present small solenoid valve, a stem is coupled to a solenoid plunger, and a valve body is attached to a distal end of the stem. A circular-ring shaped valve seat on which the valve body is seated is provided in a valve chamber of a valve casing, and a seal ring is externally fitted on the stem between the valve chamber and the solenoid plunger with an outer peripheral portion of the seal ring made to contact with an inner surface of the valve casing. The valve casing and the seal ring are made of a rubber-like polymer elastic body, a first port is connected to communicate with the valve chamber, and a second port is connected to communicate with an inner side of the valve seat. At actuation of the solenoid, when the stem moves in an axial direction, the seal ring follows the movement by only elastic deformation without sliding.

A multiple coil solenoid valve (100) is provided. The multiple coil solenoid valve comprises a first solenoid coil (101A) and at least a second solenoid coil (101B). One or more magnetic cores (210) are positioned at least partially between the first and second solenoid coils (101A, 101B). The multiple coil solenoid valve (100) also includes one or more movable armatures (211) movable between a first position and at least a second position. The one or more movable armatures (211) are positioned at least partially between the first and second solenoid coils (101A, 101B).
Abstract:
A door closer, in particular a hinge door closer, including a locking function or free-swing function, having a door closer housing, an output shaft to be connected to a door, a piston assembly connected to the output shaft and guided in the door closer housing, a closer spring, a piston rod adapted to connect the piston assembly to the closer spring, a hydraulic lock compartment adapted to lock the closer spring, and solenoid control valve, in particular a 3/2-solenoid control valve. A closure damping compartment is formed between the door closer housing and the piston assembly on a side of the piston assembly facing away from the piston rod, and wherein the solenoid control valve controls at least the pressures in the closure damping compartment and in the lock compartment.
Abstract:
A pressure balanced solenoid operated valve includes a solenoid portion having a coil. A valve member portion is connected to the solenoid portion. The valve member portion has a body including: first and second valve seats; a first cavity positioned between the first valve seat and a valve outlet port. A valve member slidably disposed in the body has a resilient valve element positioned between the first and second valve seats, the resilient valve element when in direct contact with the first valve seat defining a valve closed position. A bleed port created in the body between the first valve seat and the valve outlet port and opening into the first cavity provides a flow path for a pressurized fluid present at the second valve seat in the valve closed position to continuously flow out through the valve outlet port.
Abstract:
A diaphragm sealed, pressure balanced valve assembly includes a valve body and a cartridge connected to the valve body. The cartridge includes a cartridge loading end having a retaining member engaged to the cartridge loading end. A valve member slides coaxial to a longitudinal axis of the valve body. A resilient material first diaphragm is connected to and extends diametrically outward from the valve member having a diaphragm body clasped between the retaining member and the cartridge loading end, creating a first diaphragm fluid pressure boundary. A resilient material second diaphragm is connected to and extends diametrically outward from the valve member at an opposite end of the valve member with respect to the first diaphragm and has a diaphragm body clasped between first and second adjustable retention members, creating a second diaphragm fluid pressure boundary.
Abstract:
A piston is configured by a piston body and a support such that the piston is divided, along a direction of axis line, into the piston body, which is formed integrally with a valve element, and the support, which is provided separately from the valve element. A piston ring, which slides along a body, is held between the piston body and the support. The piston body is constantly in contact with one side face of the piston ring, and the support is constantly in contact with the other side face of the piston ring.
Abstract:
A combination thermal management valve for management of the flow of heat transfer media is provided. The thermal management valve includes a manifold including two or more independently controlled valve assemblies configured to fluidly isolate the heat transfer media from each other. The valve assemblies may be configured to maintain desirable flow characteristics for each thermal medium.
Abstract:
A configurable actuation-orientation valve (100) includes a valve body (120) including a valve bore (126) and a coil (180), a first port (101) and a third port (103) located at a first end (111) and a second port (102) located at a second end (112), a pole piece (138), an armature (130) configured to move in response to energization of the coil (180), and a biasing device (135) between the pole piece (138) and the armature (130). When the biasing device (135) is selected to provide a normally-closed biasing force to the armature (130) then the configurable actuation-orientation valve (100) comprises a normally-closed (NC) valve and when the biasing device (135) is selected to provide a normally-open biasing force to the armature (130) then the configurable actuation-orientation valve (100) comprises a normally-open (NO) valve.
Abstract:
A hydraulic solenoid control valve, including a valve housing, a valve chamber, having a first valve seat bore as a connection to a first line, a second valve seat bore as a connection to a second line, and a free aperture to a third line, a solenoid, and a valve spindle movable by the solenoid and partially arranged in the valve chamber. The valve spindle includes, a first sealing surface facing the first valve seat bore and a second sealing surface facing the second valve seat bore. The first and the second valve seat bores can be closed. The valve spindle protrudes from the valve chamber through the second valve seat bore toward the solenoid. When the second valve seat bore is closed, the valve spindle is pulled into the second valve seat bore by a differential-area-ratio through the pressure in the second line.
