Term " contactless range sensor " is interpreted as the transducer not needing mechanical organ to find range.Contactless range sensor such as comprises photoelectricity minor transducer, acoustic sensor, inductance type transducer and capacitance type sensor.Photoelectricity minor transducer also referred to as optronics formula transducer comprises at least one light source as transmitter and at least one light-sensitive element as receiver.
Contactless range sensor is used, so contactlessly measure the liquid level of coolant owing to replacing mechanical pressure switches according to ejector system of the present utility model.Because the mechanical device being subject to Effect of Rotation is not used for measuring, so can contactlessly measure continuously.By monitoring the minimum and maximum occupied state of the coolant circulated in ejector system continuously, can to identify as soon as possible in reflector cooler and fault in cool cycles and in reflector housing.This fault is such as due to the occupied state problem producing gas (cooling fluid is overheated) in liquid cooling medium undesirably and cause due to blow-by.
According to the particularly advantageous design of the one of ejector system, described contactless range sensor is designed to photoelectronic range sensor.Described photoelectronic range sensor is preferably designed for so-called " reflective sensor (Reflextaster) " at this, namely there is housing, be wherein furnished with at least one transmitter (light source) and at least one receiver (light-sensitive element).
According to a kind of preferred implementing form, described photoelectronic range sensor is designed to infrared sensor.This range sensor structural design simply and therefore correspondingly reliable.
For special applicable cases advantageously, described photoelectronic range sensor is designed to laser sensor.
In the particularly preferred design of one, in described compensation vessel, be furnished with the piston of the spring of band pretension.In this case, only detected the position of piston in an advantageous manner by contactless range sensor, to obtain the very accurately occupied state display of coolant in expansion vessel thus.Because the shape of piston remains unchanged when ejector system rotates, so this form of implementation is particularly suitable for being used in CT system.
At this particularly advantageously, described contactless range sensor is arranged between piston and the upper inside wall of compensation vessel.
But described contactless range sensor is not must be arranged in the upper inside wall of compensation vessel.Therefore, described contactless range sensor such as also can be arranged in the side inner walls of compensation vessel.
Another kind of favourable form of implementation is, described piston remains in upper position under the maximum occupied state of compensation vessel.Due to the spring of pretension, piston automatically declines when the liquid level of coolant reduces.
In another kind of design, described piston has film towards the side of coolant.Thus with simple and effective mode guarantees that do not have coolant enters the upper area of compensation vessel from piston by-pass flow and make the measurement of occupied state make a mistake thus between the outer wall and the inwall of compensation vessel of piston, namely.
In scope of the present utility model, described coolant can be liquid coolant or the coolant of gaseous state.
