Abstract: The present invention relates to an ejector assembly and a vacuum pump, the ejector assembly including a typical cylindrical vacuum ejector and a support part. The support part includes a first support having a supply line extending outwards from a hole in which a first end of the ejector is mounted, and a second support having a discharge line extending outwards from a hole in which a second end of the ejector is mounted. Further, the first and second supports facing each other are configured such that the outer circumferential surfaces thereof are in contact with the inner circumferential surface of a pipe member so as to form a space between the first and second supports, the space communicating with through holes. In the vacuum pump using the ejector assembly, the pipe member is a housing, and the space is a vacuum chamber formed in the housing.

Abstract: The present invention relates to a vacuum pump and, more specifically, to a vacuum pump that is designed to change the direction of an intake port formed on a side wall of a housing, according to necessity. The vacuum pump includes: a housing; an ejector part embedded in the housing; and a pressing means provided on the outside of the housing. Particularly, the housing includes two or more parts, including a main part that has the intake port, which are disposed in a line, wherein a stopping member is formed along a contact surface there between. This structure enables the main part to rotate, and thus the direction of the intake port can be changed.
