TL;DR: In this article, a pre-loader against an internal shoulder on the valve body to maintain precision of the stator-armature working gap during the useful life of the valve is described.
Abstract: The solenoid portion of a solenoid-operated valve is resiliently biased by a pre-loader against an internal shoulder on the valve body to maintain precision of the stator-armature working gap during the useful life of the valve. Several embodiments of pre-loader are disclosed, including a Belleville spring, a wave spring, and an elastomeric ring.

TL;DR: In this paper, a general method for the preliminary design of fast-acting solenoid actuators is described, where moving armature, drive circuit and nonlinearities are modeled as well as eddy currents for solid iron devices.
Abstract: The paper describes a general method for the preliminary design of fast-acting solenoid actuators. Moving armature, drive circuit and nonlinearities are modeled as well as eddy currents for solid iron devices. The electromagnetic model is obtained by computing two magnetisation characteristics corresponding to the extreme positions of the armature and a novel interpolation function for the intermediate positions. This function, characterising the magnetic configuration of the actuator, is computed analytically and leads also to an analytical formulation of the magnetic force. In order to achieve extremely fast computation, eddy currents are modeled through a new type of electric equivalent network, derived directly from Maxwell's equations and taking into account the actual BH nonlinearities, moving armature and device geometry. The method is demonstrated on a pot-core solenoid actuator and compares favourably with finite element results and measurements.

TL;DR: In this paper, the Gaussian process regression (GP regression) method was developed to simulate the central magnetic flux density in a Gaussian manifold with finite element methods that require a significant amount of inputs and computation resources.
Abstract: The central magnetic flux density is usually simulated via finite element methods that require a significant amount of inputs and computation resources. We develop the Gaussian process regression (...

TL;DR: In this paper, a solenoid operated control valve in an automatic transmission is operated by dither current and a flow rate of oil through the control valve is calculated, at least either one of the frequency and amplitude of the dither currents is corrected by the flow rate.
Abstract: A solenoid operated control valve in an automatic transmission is operated by dither current. A flow rate of oil through the solenoid operated control valve is calculated. At least either one of the frequency and amplitude of the dither current is corrected by the flow rate. The solenoid operated control valve is operated by the dither current.
