Title: Control valve for heat regulation
Inventor: ARVIDSSON THOMAS
IPC: G05D23/01
Filed: 2018-04-09
Abstract: The present disclosure relates to a control valve for heat regulation comprising a housing (3) with a fluid inlet (5) and a fluid outlet (7). A first valve arrangement is provided, comprising a first valve member (25) and a first valve seat (27), regulating a fluid flow based on a thermostat setting as well as a second valve arrangement, comprising a second valve member (11) and a second valve seat (13), regulating a fluid flow based on a fluid pressure difference between the fluid inlet and the fluid outlet. The second valve seat (13) is ring-shaped and the second valve member (11) reaches through the second valve seat (13) against the flow direction, such that an increase in said fluid pressure difference causes the second valve member (11) to move in said flow direction towards the second valve seat (13), thereby constricting the fluid flow. Accurate pressure difference control can be achieved as the first valve member senses the pressure of the incoming water.

Title: Systems and methods for detecting turn-to-turn faults in windings

IPC: H02H7/045
Filed: 2017-02-09
Abstract: Embodiments of the disclosure relate to detecting turn-to-turn faults in one or more windings of various objects. In one implementation, a fault detector receives a set of current measurements associated with a transformer (310; 410) and uses these measurements to execute a procedure for detecting a turn-to-turn fault in the transformer. The procedure can include dividing (820) a steadystate differential current value by a steady-state voltage value to obtain one or more compensating factors, determining (825) a magnetizing current amplitude indicator by multiplying the steady-state voltage value by the one or more compensating factors, determining (830) a compensated differential current value by combining the steady-state differential current value with a modifier value that incorporates the magnetizing current amplitude indicator, comparing (835) the compensated differential current value against a threshold value, and declaring (840)an occurrence of the turn-to-turn fault in the transformer when the compensated differential current value exceeds the threshold value.

Abstract: In a drive slip control device for a road vehicle, which is provided with an anti-lock system operating on the pump-back principle and having a return pump of the anti-lock system associated with the brake circuit of the driven vehicle wheels used as the auxiliary pressure source for the drive slip control, for braking a vehicle wheel tending to spin. When the drive slip control is activated, the main brake pipe of the brake circuit of the driven vehicle wheels is shut off from the brake unit by means of a drive slip control valve. The return pump is activated and is shut off from the brake unit until the drive slip of one of the driven vehicle wheels exceeds a threshold value whose magnitude lies between the drive slip required value and threshold response value. The brake pressure control valves of the brake circuit of the driven vehicle wheels are driven into their closed position by means of this anticipatory activation of the return pump. This causes high pressure to build up in the main brake pipe, which is limited to a value of the anti-lock braking system and of the brake equipment by means of a pressure limiting valve, which is then available for an introductory brake pressure build-up phase of the drive slip control on the vehicle wheel requiring it. An additional outlet valve, by means of which the return line of the rear axle of the anti-lock system can be directly connected to the brake fluid reservoir, can be provided for controlling the pressure reduction phases.
