Problems solved by technology

[0006] During operation of the vacuum pump system, it can happen that although a certain motive medium mass flow flows along the flow path, it is not sufficient for the jet pump to generate a sufficiently low pressure at the inlet connection or a sufficiently high Working state of vacuum

Embodiment Construction

[0040] figure 1 A vacuum pump arrangement 1 is shown. The device comprises a pump housing 2 in which a flow path 3 is formed. A flow path 3 connects an inlet connection 4 with an outlet connection 5 . The inlet connection 4 is placed on an inlet connection sleeve 6 and the outlet connection 5 is placed on an outlet connection sleeve 7 . The flow path 3 is located in a flow channel 8 formed in the pump housing 2 . With respect to its longitudinal central axis 9, the flow channel 8 comprises an annular or a circular cross-section at least over a section of its length, in particular over a large section of its length, more particularly over its entire length .

[0041] A certain fluid flows from the inlet connection 4 along the flow path 3 to the outlet connection 5 when the vacuum pump device 1 is in operation. This fluid acts as the motive medium for the jet pump 10 which is located and installed in the pump housing 2 . In principle, injection pump 10 can be of any desire...

Abstract

The invention relates to a vacuum pump device, comprising: a pump housing in which a flow path is formed; an inlet joint (4) and an outlet joint (5) through which the inlet joint (4) and the outlet joint (5) pass through the The path is in fluid communication; and the path is provided with a jet pump (10), whereby the vacuum joint (18) is in fluid communication with the intake joint (12) of the jet pump (10) through the first check valve (22) , and is in fluid communication with the flow path (3) through a second check valve (25) located on the side of the inlet joint (12) facing the outlet joint (5), and whereby the first check valve (22) and the second check valve (25) are equipped with valve seats (23, 26) and movable valve parts (24, 27) respectively, and the valve parts (24, 27) are valve tongue doors, which aligned parallel to each other in the closed state. Furthermore, the invention relates to a method for producing said vacuum pump device (1).

Description

technical field [0001] The present invention relates to a vacuum pump device, comprising: a pump casing, a flow path is formed in the pump casing; an inlet joint and an outlet joint, the inlet joint and the outlet joint are in fluid communication through the flow path; the flow path A jet pump is arranged on the top, and the vacuum joint is in fluid communication with the intake joint of the jet pump through a first check valve, and is connected with the flow path through a second check valve located on the side of the intake joint facing the outlet joint. In fluid communication, the first check valve and the second check valve are respectively equipped with a valve seat and a movable valve member. Furthermore, the invention also relates to a method of manufacturing said vacuum pump device. Background technique [0002] The vacuum pump device can be used as an integral part of the brake system of the motor vehicle, and its main function is to form a vacuum for the brake boo...
