Embodiment Construction

[0024] figure 1 Represents a vacuum pump 1, specifically, a vane vacuum pump 1, whose inlet connector 2 is connected to a unit (not shown in the figure) that will generate negative pressure through a connecting pipeline (not shown in the figure), the vacuum pump 1 A check valve (not shown in the figure) is provided between the vacuum pump 1 and the unit, and the vacuum pump 1 is controlled by a monitoring unit (not shown in the figure).

[0025] In the present example, the vacuum pump 1 is driven electrically, for which purpose a corresponding electrical connector 3 is provided. The monitoring unit can be connected with the electrical connector. The monitoring unit causes the vacuum pump 1 to switch on and off and thus enter into an operating state.

[0026] For example, when the vacuum pump 1 is in operation, the unit that will generate negative pressure is the brake servo unit.

[0027] When the vacuum pump 1 has been in operation, it sucks the medium from the unit into t...

Abstract

The present invention relates to a vacuum pump (1), wherein the inlet connection member (2) of the vacuum pump is connected with a unit generating a negative pressure through a connection pipe line, between the vacuum pump (1) and the unit there is provided a non-return valve, and the vacuum pump (1) is provided with a monitoring unit. In order to prevent the vacuum pump from being overheated with no need for continuous operation, the lower portion of the non-return valve is provided with a hole (5), and the hole (5) is enclosed when used for meltable materials (6, 8) fused at a pre-defined melt temperature and for sublimable materials (6, 8) sublimated at a pre-defined sublimating temperature. The originally-enclosed hole (5) is opened through the melted or sublimated meltable or sublimable materials, thereby being convenient for the vacuum pump (1) to inhale fresh air for cooling.

Description

technical field [0001] The present invention relates to a vacuum pump, in particular to a vane cell vacuum pump, the inlet connector of which is connected to the unit through a connecting pipeline, and negative pressure will be generated in the unit, and a check valve is arranged between the vacuum pump and the unit. The vacuum pump can be controlled by the monitoring unit. Background technique [0002] Both patent documents DE 10 2004 012 736 A1 and DE 2 356 398 disclose fusible security devices, neither of which is relevant to the class of this patent. [0003] In automotive technology, vacuum pumps are known, in particular vane vacuum pumps, which are able to generate a negative pressure in the brake servo (unit). Therefore, the basic structure of the vane vacuum pump will not be discussed in detail. [0004] It is known that these vacuum pumps can be driven electrically, their operation being controlled by a monitoring unit. Thus, the vacuum pump can be turned on and ...
