摘要： The invention refers to an en ejector which is operative for generating a sub- pressure, the ejector having a rotationally symmetric ejector body (1) arranged to be mounted in the mouth of a seat (8) having a circular internal section, such that in a mounted position an inlet end (2) of the ejector body is inserted in the seat and an outlet end (3) thereof projects outside the mouth of the seat. The ejector body (1) comprises on its exterior a region (23) of defined axial length with a radius that is growing towards the inlet end (2), the region being situated between inlet and outlet (23) ends, as well as a shoulder (24) having an abutment surface facing said region, the shoulder being arranged on the ejector body near the outlet end (3) thereof. The ejector is arranged for supporting a cylindrical clamping sleeve (26) for a limited axial displacement about the ejector body, between the shoulder (24) and said region (23) of growing radius, whereby the ejector can be arrested together with the sleeve having an expandable sleeve wall, an inner radius of which is dimensioned for expanding the sleeve radially as the sleeve is displaced with respect to the ejector body into said region, and an outer radius of which is dimensioned for clamping the sleeve between the ejector body and the seat wall upon the resulting radial expansion. By analogy therewith, the invention relates also to a method for mounting an ejector body (1) having a rotationally symmetric exterior in a seat with cylindrical section.

摘要： So as to render the manufacturing of an at least equally efficient multi-stage ejector more cost-efficient, the invention provides a multi-stage ejector for generating a vacuum from a source of compressed air by passing said compressed air through a series of nozzles, accelerating said compressed air, and entraining air so as to form a jet flow in one or more stages and generate a vacuum across each stage, the multi-stage ejector comprising a drive stage; a second stage; and a converging-diverging nozzle provided in said series of nozzles between said drive stage and said second stage for receiving jet flow from said drive stage and accelerating said jet flow to form a second stage air jet and directing said second stage air jet into an inlet of an outlet nozzle of the second stage, wherein said converging- diverging nozzle is formed in a moulded nozzle piece mounted in said multi-stage ejector.

摘要： So as to more rapidly accelerate the air flow in a vacuum ejector to supersonic speed whilst focussing the exiting flow of air to downstream of the exit of the nozzle, the invention provides an ejector for generating a vacuum comprising, a drive nozzle for generating a drive jet of air from a compressed air source and directing said drive jet of air into an outlet flow passage at the outlet of a drive stage of the ejector in order to entrain air in a volume surrounding said jet of air into the jet flow to generate a vacuum across said drive stage, wherein said drive nozzle substantially consists of an inlet flow section and an outlet flow section aligned in a direction of air flow through the nozzle, the outlet flow section diverging in the direction of airflow, from an outlet end of the inlet flow section substantially to an exit of the nozzle, the outlet flow section having a shape which is more divergent near the outlet of the inlet flow section and less divergent near the exit of the nozzle.

摘要： The present invention relates to handling devices for handling foodstuffs, which may include a suction cup and a docking piece supporting the suction cup. The suction cup may be removably attached to the docking piece. The docking piece may include a drive nozzle inserted into the suction cup, and attached to the docking piece, for ejecting a fluid from the drive nozzle inside of the suction cup. The suction cup may include a drive opening for receiving the drive nozzle of the docking piece, and an outlet nozzle having at least one constriction. The outlet nozzle is aligned with the drive nozzle so that the drive nozzle and the outlet nozzle cooperate to form an ejector. The ejector then applies a suction force to the surface of the foodstuff which is to be handled.

摘要： A bellows insert (25) is shown, mountable inside a bellows for a vacuum powered tool and, in the mounted position, effective to locally limit the capacity of the bellows of compression in its longitudinal direction caused by a negative pressure introduced into the bellows. The bellows insert comprises an engagement part (26) that has a shape complementary to the inside of the bellows and that, in the mounted position of the bellows insert, fills up some or all of the pleats of the bellows within a limited area of the circumference of the bellows.

摘要： A vacuum generator driven by compressed air and arranged to supply vacuum to a vacuum gripper means, wherein a chamber (6) is associated with the vacuum generator and arranged to be brought in flow connection (9) with the vacuum gripper means via a valve (15) which is actuated by overpressure accumulated in the chamber to open said connection (9) to the vacuum gripper means in order to discharge the overpressure to the vacuum gripper means in result of interruption of the compressed air flow (P). The vacuum generator is characterized in that said chamber (6) in addition comprises a flow connection (11) with the ambient atmosphere, and in the additional flow connection (11) a one-way valve (10) which is arranged to open the connection (11) with the atmosphere in result of the air pressure in the chamber (6) falling below the atmospheric pressure.
