Abstract: A rotational control device for the setting of angles in actuators, in particular of a restricting device used for determining the flow cross-section in a flow line for internal combustion engines, has an electrical setting motor with a two-pole status and a two-pole permanent magnet rotor. To obtain a robust setting motor, which is technically easy to manufacture in a compact construction, the stator poles are designed as claw poles and the stator winding is located as a toroidal coil in a ring space formed by the claw poles and a ring casing which is coaxial with these, for the magnetic return path. The stator winding is energized by a d.c. supply, with reversible current direction. The magnetic resistances in the magnetic return path and across the claw poles are calibrated such that in the event of a currentless stator winding, the permanent magnet rotor engages in the pole gaps between the claw poles.

Abstract: A rotary actuated valve choke or the like is remotely controlled by motor means fixedly mounted with respect to said valve to rotationally drive a stem thereof. Monitoring means measure the rotation of the motor and/or its associated drive train. The monitoring means convert the rotary motion to a more easily measurable linear motion to measure the valve setting and appropriately control the energization of the motor in response thereto.

Abstract: A control device for the control of an opening cross-sectional area of a flow duct, in particular for internal combustion engines, comprising three sub-assemblies, an actuator housing with flow channel and setting window, a rotor with a rotary valve for controlling the window opening, and a drive housing with stator and stator winding. For setting a required air gap between the rotary valve and the setting window, a control section of the rotary valve covering the setting window is designed as a cone envelope segment, and is inclined at an acute angle to the rotor axis. The window lying in a cone envelope plane is located at the same angle of inclination. By means of a spacing disk between the rotor, with the rotary valve affixed thereon, and the actuator housing, the air gap is set and fixed as required.

Abstract: A proportional solenoid-controlled valve provides for precise control of fluid flow using a flat spring and a damper. The flat spring is three-lobed and is constrained on its outer diameter in one of six degrees of freedom. The damper has three outer lobes which are compressed between the armature assembly and the valve body. A spring-loaded seal configuration having an annular elastomer seal compensates for dimensional instability of the elastomeric seal material and the armature assembly.

Abstract: A linearly adjustable fluid damper of the sliding plate adjustable orifice type damper system having a fixed flat plate with a plurality of specifically arranged trapezoidal shaped apertures therethrough, and a slideably adjustable flat plate also having a plurality of specifically arranged trapezoidal shaped apertures therethrough. The sliding plate is juxtaposed the fixed plate such that apertures of the sliding plate overlap apertures of the fixed plate, and aperture orientation of the sliding plate is reversed that of the orientation of the apertures on the fixed plate. The area of the resultant hexagonal composite orifice through both plates varies non-linearly from full open position to full closed position throughout movement of the sliding plate. The result is that fluid flow from zero fluid flow to maximum fluid flow through the resultant orifice is a straight line relationship with linear displacement of the sliding plate.

Abstract: The valve has a casing with inlet and outlet ports, and a valve opening bordered by a valve seat communicating the ports. A flexible diaphragm defines a control chamber and a pressure chamber on opposite sides thereof and moves between an open position clear of the seat, and a closed position against the seat. The valve seat is within the pressure chamber, and the diaphragm is normally urged closed. A flexible bellows extends between and is sealed to the diaphragm and the casing on a side of the diaphragm remote from the seat. The bellows provides a bellows chamber isolated from the control chamber to enclose an effective area of the diaphragm generally equal to the valve opening of the valve seat. The diaphragm has an orifice providing limited communication between the control and pressure chambers and having a size sufficient to reduce fluid flow between the chambers to reduce diaphragm speed and thus chances of hydraulic hammer.
