Hydraulic fluid boiling point determination method, especially for brake fluid in a motor vehicle braking system, whereby a micro pump is used with an electrical heating element that acts as a pump actuator

摘要

Device for determining the boiling point of the hydraulic fluid of a hydraulic system, especially brake fluid in a motor vehicle braking system, comprises an electrical heating element (24) that is placed in the brake fluid and which also acts as an actuator for a micro pump and is placed in a chamber (14) of the pump. An Independent claim is made for a method for determining the boiling point of brake fluid, whereby a heating element in a chamber of micro pump causes fluid to be transported into the chamber where it is heated by the electrical resistance of the heating element and the boiling point determined.
