Apparatus and method for controlling fluid flow

Номер: US20120068096A1
Автор: Kay Herbert, Natan E. Parsons, Xiaoxiong Mo
Принадлежит: Individual

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.

A valve unit capable of being implanted in a patient and having adjustable performance settings, such as pressure settings and/or flow control, to regulate passage of a bodily fluid. A casing defines a port for the bodily fluid, and a valve mechanism positioned at the port includes a movable valve member. The valve unit further includes a rotor disposed at a first location in the casing and having an axle which turns about an axis of rotation. The rotor defines a plurality of arcuate, radially flat cam surfaces. Each cam surface occupies an arc about the axis of rotation. A spring arm unit is disposed at a second location in the casing having a cam follower arm in slidable contact with the cam surfaces of the rotor and having a resilient spring element applying a closing effect with the movable valve member to establish a performance setting for the valve unit. Sufficient rotation of the rotor to change the cam surface in contact with the cam follower alters the closing effect with which the valve member moves relative to the port and thereby alters the performance setting of the valve unit.

Method for Detecting a Closing Time Point of a Valve Having a Coil Drive, and Valve

Номер: US20140069533A1
Автор: Görzen Johann

A method for detecting a closing moment of a valve having a coil drive includes impressing an electrical voltage in the exciter coil to generate an exciter current through the coil, which attracts the movable armature and lifts the valve element off its valve seat. After the exciter current decays to zero, the voltage profile at the exciter coil is sampled and read out over time in the form of time value/voltage value pairs. The detected voltage values and time valves are transformed by the formation of a logarithm to form a transformed function. The transformed function is subsequently derived numerically with the formation of a derivation function. A transformed time value corresponding to the valve closing moment is detected based on the derivation function of a predetermined threshold value S being undershot, and the closing moment is calculated therefrom by inverse transformation. 2.
