Abstract
The invention relates to a vacuum pump, in particular a vane cell pump, having a housing in which a suction space is provided, and a housing passage opening into the suction space, wherein a suction non-return valve opening to the outside or into an external vacuum space is arranged in the housing passage, said valve being accommodated in a pot-shaped housing, the pot-shaped housing having a housing bottom and a housing jacket, wherein the housing bottom is integral with the housing jacket.
Claims
exact text as granted — not AI-modified1 - 10 . (canceled)
11 . A vacuum pump or a vane cell pump, the pump comprising:
a pump housing defining a suction space and having a pump housing passage, opening into the suction space; and a suction non-return valve configuration disposed in said pump housing passage, said valve configuration opening to an outside or into an external vacuum space, wherein said valve configuration comprises a suction non-return valve disposed in a pot-shaped valve housing having a housing bottom and a housing jacket, said housing bottom being integral with said housing jacket, wherein said housing bottom of said pot-shaped valve housing has an edge that extends said housing jacket beyond said housing bottom, said valve configuration further comprising a holding disk that is pressed into an intermediate space formed by said edge that protrudes beyond said housing bottom, wherein a valve body is disposed between said housing bottom and said holding disk.
12 . The vacuum pump of claim 11 , wherein said housing bottom has a mounting location for a holding section of said valve body.
13 . The vacuum pump of claim 12 , wherein said mounting location is constituted as an opening.
14 . The vacuum pump of claim 12 , wherein said mounting location penetrates right through said housing bottom.
15 . The vacuum pump of claim 12 , wherein said mounting location has a hollow cylindrical or a regular cylindrical cross-section.
16 . The vacuum pump of claim 12 , wherein said mounting location is constituted without undercuts.
17 . The vacuum pump of claim 12 , wherein said valve body comprises elastic, rubber-elastic, stainless steel or spring steel.
18 . The vacuum pump of claim 12 , wherein said holding section is constituted in the shape of a pin or in the shape of a cylinder.
19 . The vacuum pump of claim 11 , wherein said holding disk retains said holding section in said housing bottom.
20 . A suction non-return valve for the vacuum pump of claim 11 .Join the waitlist — get patent alerts
