Definitions

Such an oil circuit can be made significantly simpler if the bypass line takes over the function of the short-circuit line, since the latter can then be omitted.
the flow determining element provided in the bypass line is a simple throttle, the flow cross section of which is matched to that of the oil cooler pipes.
the pressure control valve provided in DE 37 14 230 A1 can therefore be omitted without replacement.
the respective flow cross-sections are coordinated with one another, taking into account the respective temperature-dependent oil viscosity, so that only the bypass line is acted upon in the case of cold oil and the oil cooler pipes are primarily acted on in the case of hot oil.
Such an oil circuit uses the known advantages of the bypass line described above and at the same time offers high security in the event of a failure of the thermostatic element controlling the short-circuit line or bypass line. If this thermostatic element should always remain in its position blocking the oil cooler pipes, then at least one arises through the bypass line slight oil cooling, which significantly reduces the risk of the oil overheating and thus the risk of damage to the machine or vehicle.
the thermostatic element controls only the flow cross-section of a supply line or return line leading to the oil cooler pipes. If the throttle cross-section is adjusted differently, it is also possible to influence the flow cross-section of the bypass line by the thermostat element alone. In this case, the actuator of the thermostat element can also take over the function of the throttle with a suitable geometric design. At this point, the state of the art known from DE 37 14 230 A1 will be discussed again. Also there is shown in an alternative embodiment the possibility of designing the flow determining element of the bypass line as a thermostatic valve, but two thermostatic valves are still required there, while a single valve is sufficient in the configuration according to the present invention.
this thermostatic element has an actuator which controls the flow cross-section of the bypass line simultaneously with and in the opposite direction to the flow cross-section of the feed line or return line to or from the oil cooler pipes.
the actuator can of course also take over the function of the bypass line throttle.
the heat transfer connection between the bypass line and the oil cooler pipes is preferably made via the header boxes for the oil cooler pipes.
the bridging line can be flanged directly to the wall of a collecting tank or be integrated in this, but it is also possible for the bridging line to essentially completely cross a collecting tank. This traversing can take place in a separately inserted pipe, but it is also possible that the collecting box itself forms part of the bypass line.
the actuator 11 assumes different positions. In the position shown, the actuator lies against its left stop under the influence of a compression spring 12 and thus releases an outlet opening 13 of the return line 7b. Under the influence of a wax element, not shown, the actuator 11 can also be moved to the right against the force of the compression spring 12, so that the outlet opening 13 is closed.
