摘要： A rectilinear motion solenoid having a housing, an annular coil of electrical wire mounted in the housing and having a central hole therethrough. A first magnetic pole piece is oriented adjacent a first axial end face of the annular coil and a second magnetic pole piece oriented adjacent a second end face of said annular coil. An armature is movably mounted in the central hole. Two substantially linear springs are provided for securing the armature to the housing to effect a frictionless resilient suspension of the armature in the central hole. A closed chamber is filled with a liquid so that a disk movable with the armature is also movable in the chamber. A perimeter of the disk is oriented in close relation to an interior wall surface of the chamber to define a liquid flow restricting gap therebetween and effecting during operation a dynamic dampening of armature movement.

摘要： A solenoid with liquid in the gaps between a moving and stationary element is disclosed that includes a secondary kick-back spring used to overcome the viscosity and surface tension effects of the liquid in the gap during the de-energizing phase of the solenoid action. Various secondary spring designs as well as surface shapes of the butt or plunger ends are possible in order to decrease the contact surface area of the ends of either the moving or stationary elements used in the solenoid and also are also used to decrease the viscosity and surface tension effects of the liquid.

摘要： An apparatus that controls impact noise of a solenoid by energy dissipation through both resilient and pneumatic devices. This is achieved by providing a device between the plunger of the solenoid and a machine member. The device includes a predetermined number of orifices which are of different sizes and placed at different locations. This forms an air metering system and controls the stiffness of the device for maximum impact noise attenuation.

摘要： The electromagnetically operated valve communicating with a pressurized fluid in an oil-filled chamber, includes an armature (17) resiliently retained in an armature chamber (16) of a housing (10) by membrane springs (22,23); an armature-operated valve body (20) movable with clearance in a hole (34) provided in the housing (10) and a compression spring (40) biasing the armature. The armature chamber (16) is hermetically sealed in the housing from a valve part (15) against which the valve body (20) is urged by the compression spring and contains a damping fluid for damping motions of the armature. The housing is also provided with a first compensating chamber (44) communicating with the armature chamber (16) to compensate for a volume change of the damping fluid and with a second compensating chamber (46) connected with the first compensating chamber via a duct (45). The second compensating chamber is filled with air and communicates with the oil-filled chamber filled with the pressurized fluid so that dirt and other particles in the pressurized fluid cannot reach the damping fluid of the armature chamber.

摘要： An assembly is provided for use in a solenoid having an energizable coil. The apparatus includes a ferromagnetic main body member adapted to be received in the coil. An armature chamber having a constant diameter is disposed in the main body member. A radially externally facing taper is formed in the outer surface of the main body member. The taper extends between the armature chamber and the outer surface of the main body member. A stationary pole piece and an end plug respectively define a first and second end of the armature chamber. An armature member is positioned in the armature chamber for axial sliding movement relative to and defining a working gap relative to the pole piece. The armature includes a fluid passage adapted to provide nonlaminar fluid flow. A nonferromagnetic sleeve is positioned on and fixedly connected to the main body member. The sleeve is linearly coextensive with the externally facing taper and at least a portion of the working gap sufficient to permit selected magnetic forces to be exerted on the armature member. A junction of the sleeve and the externally facing taper define an air gap which extends from the externally facing taper to an internal radial surface. The stationary pole piece and the main body member are manufactured from a single piece of ferromagnetic material and the armature chamber is formed subsequent to fixing the sleeve to the main body member.

摘要： An absorber is position on the back or opposite side of a solenoid to receive the kinetic energy of the armature. The energization of the solenoid attracts the armature to the solenoid core and upon striking the core, the kinetic energy of the armature is transferred through the core and to the absorber. The absorber is launched into flight for the purposes of dissipating the kinetic energy and returns to rest on the core without effecting the movement of the armature. The absorber dissipates the kinetic energy by transferring it to a spring means and also may dissipate the energy by means of viscous damping or the flow of fluid from one side of the absorber to the opposite side.

摘要： A bistable electromechanical transducer is disclosed having an armature reciprocable between first and second positions, a permanent magnet latching arrangement for maintaining the armature in the respective positions, and an electromagnetic repulsion arrangement operable when energized to dislodge the armature from the position in which the armature was maintained and causing it to move to the other of the positions. In a preferred embodiment, the transducer takes the form of an electronically controllable valve mechanism for use in an internal combustion engine and has an engine valve with an elongated valve stem along with the electromagnetic repulsion arrangement for causing the valve to move in the direction of stem elongation between valve-open and valve-closed positions. An arrangement for decelerating the valve as the valve nears the respective valve-open and valve-closed positions includes at least two separate damping arrangements jointly effective to slow valve motion as the valve gets close to said one position. The damping may include dynamic breaking and energy recovery. The mechanism may also include a housing at least partially surrounding the valve stem and an arrangement for circulating the engine liquid coolant through a portion of the housing.

摘要： A solenoid bumper mechanism wherein a resilient means absorbs a proportion of the kinetic energy of a shaft moving within the solenoid, and a nonresilient means which causes the shaft to terminate its movement at a fixed point.

摘要： A print mechanism has a laterally spaced longitudinally driven actuator or slider mounted between two electromagnets. By selective actuation of the electromagnets the slider is driven forward to strike a print element and produce printed information. A unique dampener assembly is provided to absorb recoil energy and maintain a fixed start position. The dampener assembly includes a return spring and a three layer damper that absorbs the excess recoil energy without experiencing permanent deformation.
