Disclosed are embodiments of a pinch valve assembly that can include a controller, an actuator assembly, the actuator assembly including a stepper motor, a leadscrew actuated by the stepper motor such that the leadscrew travels in a plurality of incremental linear steps, a piston coupled with the leadscrew such that relative movement of the leadscrew is transferred to the piston, a valve body, where the piston travels within a bore defined by the valve body, a slotted aperture formed in the valve body to retain at least a portion of tubing, and a pin where the piston and the pin are configured to pinch tubing therebetween such that flow within the tubing can be metered.

A pilot check valve includes: a fluid channel body; a moveable body that moves in an axial direction under effects of pilot pressure; a packing including a lip portion that is displaceable, integrally with the moveable body, between a valve close position and a valve open position; and a detector to detect position of the moveable body. The packing, in the valve close position, allows flow of an operating liquid from a first port side of the fluid channel body to a second port side and prevents the flow of the operating liquid from the second port side to the first port side, and in the valve open position, connects the first port and the second port.

The present disclosure provides a rotational angle detecting device. An IC substrate has a flat surface extending along a rotational axis of a throttle valve. Yokes forms, together with the magnets, a closed magnetic circuit. A first Hall element outputs a first signal according to the magnetic flux density in a first direction along the flat surface. A second Hall element outputs a second signal according to the magnetic flux density in a second direction intersecting the flat surface. The first and second Hall elements are positioned within a region that is surrounded by the magnets and the yoke and that is between an edge surface and an edge surface.

A method and system for determining a position of a linearly translating member. The method may comprise transmitting an excitation into a linearly translating member through one or more couplers from an acoustic device disposed in an outer housing, recording a reflected excitation from the linearly translating member with the acoustic device, and identifying a position of the linearly translating member with respect to the acoustic device. The system may comprise an outer housing, a linearly translating member disposed within the outer housing, an acoustic device disposed in the outer housing and configured to transmit an excitation at various frequencies and various amplitudes and record returned excitation frequencies and amplitudes and time of travel, and an information handling system in communication with the acoustic device.

Valve including a valve body with an inlet port and two outlet ports, a core capable of allowing or interrupting the flow of fluid between the inlet port and the outlet ports, the core being rotatably movable about a longitudinal axis and configured to assume two end angular positions, a gear motor comprising an output shaft driving the core, sensors for managing the electric motor mounted to a first, facing electronic board, an angular position sensor of the output shaft, mounted to a second electronic board, the first electronic board and the second electronic board being disposed in two distinct planes orthogonal to the longitudinal axis, a magnet rotatably attached to the output shaft, the position and angular extension of which are such that the magnet does not disturb the operation of the management sensors.

A method of adaptively sampling data to determine the start of injection in a solenoid actuated valve of a fluid injector includes, in an operating cycle or portion thereof of the valve, sampling the signal of current through a solenoid of the valve at sampling points having a pre-defined interval therebetween. At each sampling point, determining the value of the first derivative of current and detecting the sampling point at which the first derivative achieves a maximum as the start of injection. Values of the first derivative of the sampling points immediately preceding and immediately following the start of injection are determined. In a subsequent operating cycle, synchronisation of sampling is altered to shift sampling times depending on the values of the first derivative of the sampling points immediately preceding and immediately following the start of injection.

A valve gear box has a valve monitoring function. The valve gear box is for mounting to a valve that has a fluid passageway and a gate therefor, the gear box providing a gear driven link for moving the gate between open and closed conditions of the fluid passageway, the valve gear box being in a housing that has a mounting for permitting operative connection to the valve via a mounting flange of the valve. The mounting and the mounting flange have a valve monitoring sensor operatively positioned therewith, the sensor being settable in one state when the mounting and the mounting flange are in assembled relationship to each other but being configured to change from the one state if there is a separation of the fastened connection of the mounting and the mounting flange, whereby a change in state from the one state can be used to monitor a separation of the assembled relationship of the mounting and the mounting flange and trigger an alarm condition.

The present invention provides a system for determining plunger position in a solenoid valve and method therefore. More specifically, the invention provides a solenoid valve having hall sensor for detection of plunger position, which provides feedback including output voltage (digital or analog) respective to its position. The solenoid valve includes a nozzle, a spring, a sealing rubber, a poppet, a magnetic bracket, a rubber grommet, a housing sub-assembly, a soft seal, a sensor assembly, a fix core, a moving core and/or plunger, coil, a bobbin sub-assembly, a fix core plate, magnet holder, a permanent magnet and plurality of terminals.

A valve assembly is disclosed, and includes an evacuator and a relief valve. The evacuator includes a suction port that selectively applies a vacuum. The relief valve has an open position and a closed position, and includes an inlet, an outlet, a piston that translates within a chamber, and a pressurized chamber. The piston includes a first end and a second end. The pressurized chamber is fluidly connected to the suction port of the evacuator, and is defined in part by the first end of the piston. The piston translates within the pressurized chamber towards the open position if vacuum is applied to the pressurized chamber.
