A non-contact transport apparatus includes a housing and a plate which is fitted into a circular recess formed at a central portion in a lower surface of the housing. The housing is formed in an octagonal shape corresponding to the shape of a workpiece to be transported. In the plate, a plurality of nozzles are arranged radially at equal angular intervals. The nozzles include first nozzle grooves and second nozzle grooves having cross sectional areas that are determined in proportion to distances between a principal side of the housing and the nozzle and between an oblique side of the housing and the nozzle for making the flow rates of the pressure fluid through the first nozzle groove and the second nozzle groove different.

Non-contact transport apparatus

An inner member having a supply port is installed at the inside of a housing, wherein the housing and the inner member are connected together by connecting bolts. Air is supplied to the supply port of the inner member and is directed and introduced through communication passages into an annular passage. Thereafter, the air is directed outwardly from a plurality of lead-out holes, which communicate with the annular passage, in a swirling direction with respect to an annular recess facing the workpiece. In addition, by having the air flow along the annular recess, which is formed with a substantially trapezoidal shape in cross section, the workpiece is maintained in a non-contact state with respect to a holding surface of the inner member.

A pressure reducing valve includes a first screw member on which a nut for adjusting the spring force of a pressure regulating spring travels, and a second screw member screwed into the first screw member and provided with a stopper for limiting the travel range of the nut at the tip. The second screw member can be displaced with respect to the first screw member along its length, so that the limiting range of the stopper against the travelling nut is adjustable.

A case mounting mechanism for use on a pneumatic device such as a filter, a lubricator, or the like includes a plurality of first ridges projecting inwardly from an edge of an annular groove defined in a body, each of the first ridges having a recess, and a plurality of second ridges projecting outwardly from a peripheral edge of a case guard and each having a projection. The case guard surrounding a case is mounted on the body by engagement between the first and second ridges with the projection on each second ridge engaging in the recess of each first ridge. The case is of a cylindrical shape having a ridge projecting axially outwardly from a terminal end thereof and defining a fluid passage therein. The case guard fitted over the cylindrical case has a hole defined in a terminal end thereof. The case and the case guard are combined together with the ridge on the terminal end of the case being fitted in the hole, and have peripheral edges detachably fitted in the annular groove of the body.

Case mounting mechanism for use with pneumatic apparatus

A drainage valve unit for use with a casing for collecting a drain includes a valve body adapated to be mounted on the casing and having a fluid passage and a chamber defined therein and communicating with each other, a valve member disposed in the fluid passage and movable axially of the fluid passage for opening and closing the fluid passage, and a pusher body disposed in the chamber and movable axially of the chamber, the pusher body being displaceable from outside of the valve body for causing the valve body to open the fluid passage to discharge the drain from the casing through the fluid passage. The valve member can reliably be moved to open the fluid passage for discharging the drain by pushing the pusher body irrespective of the pressure within the casing. When the fluid passage is opened, the drain can quickly be discharged without falling on the operator's hand and fingers.
