The present invention relates to a vacuum gripper unit. The unit has a first mounting container and a second mounting container of cylindrical shapes formed in an H-type when seen from the outside, including a main body for providing a common vacuum chamber. A vacuum pump is inserted into the first mounting container, while the vacuum pump or a release valve is selectively mounted in the second mounting container. In addition, a front insertion hole of each of the first mounting container and the second mounting container is provided with a finishing material which supports each of the release valve and the vacuum pump that are mounted to thereby prevent the valve and pump from being separated. It is preferable that the finishing material of at least the first mounting container is a silencer.

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.

Ejector assembly and vacuum pump

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.

Disclosed is a check-valve assembly for use in a vacuum system. The check-valve assembly of the present invention comprises a body having a plurality of through-holes formed therein while having different space characteristics. As a valve member rotates with a shaft fixed to the body, intake holes of the valve member selectively communicate with the through-holes. Accordingly, the check-valve assembly of the present invention can more quickly respond to vacuum characteristics required on site, which is advantageous.

A quick-release vacuum pump which is mainly applied to a vacuum transport system. The vacuum pump has a mechanism in which part of compressed air supplied for generating a vacuum state is stored firstly in a chamber, and then the vacuum state within the chamber is released when transportation is completed. When the vacuum state is released, a check valve is moved by the pressure of air that flows backward. The range of movement of the check valve is adjusted by a control means. An air filter is disposed at the lower end of the check valve. The release of the vacuum state is quick and controllable. Also, the filter is naturally filtered and cleaned.
