A solenoid-operated valve includes a valve body defining a valving bore for providing a path of communication between axially spaced inlet and outlet ports. A solenoid assembly is attached to the valve body and includes an inductor coil, a fixed flux guide and an armature, which is movable axially between a first position and a second position in response to electrical energization of the inductor coil. A valve member is disposed within the valving bore intermediate the inlet and outlet ports. An elongated control member interconnects the armature and the valve member for conjoined axial movement. A generally annular valve seat is disposed within the valving bore between the inlet port and valve member, the valve seat including a central through bore through which the control member extends.

A solenoid assembly is used with a valve assembly to regulate the flow of fluid therethrough. The solenoid assembly includes a solenoid frame extending between a first end and a second end. A primary plate is disposed adjacent the first end of the solenoid frame. The primary plate includes a flux concentrating cylinder extending out therefrom. A secondary plate is disposed adjacent the second end of the solenoid frame. A bobbin is disposed within the solenoid frame between the primary and secondary plates. The bobbin defines a core and has a wire coil wrapped about the core. The wire coil receives an electric current to induce a magnetic field thereabout. The solenoid assembly also includes a plunger that is extendable through a portion of the core of the bobbin and is movable at a defined force with respect to the bobbin. The plunger moves in response to changes in the magnetic field. The plunger includes a flux extension extending out therefrom coaxially with the plunger. The flux extension includes a relief portion cut out of the flux extension to change the force created by the plunger as it moves through the core.

A method and assembly for controlling a plunger of a magnetic actuator includes generating a magnetic flux at the plunger that opposes a first bias from a first spring having a first preload. A second spring opposing the first bias is disposed in series communication with the first spring. The second spring has a second preload less than the first preload and is configured to be adjustable to control the amount of magnetic flux needed to overcome a net total preload opposing the magnetic flux. A second magnetic flux higher than the first magnetic flux is generated biasing the plunger to overcome the net total preload from the first and second springs in series communication.

Magnetic actuator and method

A sensing assembly identifies detonations in a plurality of cylinders of an internal combustion engine. The internal combustion engine includes an engine block. The sensing assembly includes a base that is fixedly secured to the engine block of the internal combustion engine. The sensing assembly also includes a sleeve that is fixedly secured to the base and extends outwardly therefrom. A sensor element extends around a portion of the sleeve. The sensor element receives vibrations generated by the detonations of the internal combustion engine and converts those vibrations into an electrical current. The sensing assembly includes a first terminal abutting the sensor element. The first terminal includes a first terminal pad directed in a first direction. The sensing assembly also includes a second terminal abutting the sensor element. The second terminal includes a second terminal pad directed in a second direction opposite the first direction such that leads connected to each of the first and second terminal pads are prevented from shorting the sensor element.

A threadless knock sensor ( ) includes a sleeve ( ) around which a transducer ( ) and a load washer ( ) are disposed. A frusto-conical disk spring ( ) is installed in compression around the sleeve ( ) above the transducer ( ). The sleeve ( ) includes threadless structure for holding the disk spring ( ) in compression.

Threadless knock sensor

A mounting fixture for an engine knock sensor is provided. The fixture includes a base and a support member. The support member is joined to the base with a press fit joint. The base includes an aperture and the support member is inserted in the aperture. The support member can be a bolt or a sleeve. The invention can also include a lip, associated with the support member for retaining a spring washer. The spring washer can be deflected between the support member and a knock sensor component for pressing the knock sensor component against the base.

A vehicle solenoid valve includes a coil case with a plunger housing disposed therein. The plunger housing establishes a first fluid communication path and a second fluid communication path. Reciprocably disposed within the plunger housing is a plunger. The plunger is movable between a de-energized configuration wherein fluid communication through the first fluid communication path is permitted and fluid communication through the second fluid communication path is blocked, an energized configuration, wherein fluid communication through the first fluid communication path is blocked and fluid communication through the second fluid communication path is permitted, and a pressure relief configuration, wherein, while the valve is energized, fluid pressure on the plunger surpasses a predetermined pressure level to overcome an opposing magnetic force on the plunger and permit fluid communication through the first fluid communication path.

Vehicle solenoid valve

A vehicle braking system has a self-apply control which is effective to control the vehicle wheels under braking situations, traction control situations and chassis control situations. The self-apply control includes an electronic control unit (ECU) to establish the operation of the brakes. A positive displacement pump is utilized to provide fluid during self-apply operation. The output pressure of the pump is controlled by a variable pressure isolation valve which is controlled by the ECU to establish the maximum pressure required during each situation such that excess fluid pressure is not generated at the pump. the isolation valve has a stepped diameter bore in which a valve spool is disposed. The valve spool and the bore cooperate to form a unique dampening structure. The valve land and the bore wall form a flow restriction to and from a dampening chamber formed by the bore step and the valve land. This dampening reduces the pressure pulsation at the pump outlet for improved performance in the brake control system.
