Abstract

An apparatus for the heating of a lubricating oil for a weaving machine contains at least one heating element with at least one semiconductor and temperature regulator with a sensor.

Claims

1. An apparatus for the heating of lubricating oil for a weaving machine, the lubricating oil being present in a container, and the apparatus containing at least one heating element and a temperature controller with a sensor,

wherein the apparatus further comprises a housing of a material with good thermal conductivity and the heating element and the temperature controller with the sensor are so arranged in the housing that the heating element is thermally conductingly connected to a housing wall, and

wherein the container consists of a material with good thermal conductivity and the housing is secured to the outer surface of the container, with a means for thermal conduction being provided between the contacting surfaces for conducting heat through the wall of the container into the lubricating oil.

2. Apparatus in accordance with claim 1, wherein the heating element is a current or voltage controlled semiconductor device.

3. Apparatus in accordance with claim 1, wherein the heating element is a current controlled semiconductor device and has a heating resistor.

4. Apparatus in accordance with claim 1, further comprising a monitoring unit which is connected to the sensor of the temperature regulator.

5. Apparatus in accordance with claim 1, further comprising a bridge rectifier for the voltage supply, with the bridge rectifier as a protection against incorrect polarity enabling operation with DC current and also AC current.

6. Apparats in accordance with claim 1, wherein a power regulator is provided.

7. Apparatus in accordance with claim 1, further comprising a bridge rectifier and a monitoring unit which is connected to the sensor of the temperature regulator, wherein the bridge rectifier, the heating element, the temperature regulator with the sensor and monitoring unit are formed as a unit.
