MEANS FOR USE IN APPLYIN ALTERNATIVELY, AIR PRESSURE AND SUCTION A GIVEN POINT Filed Sept. so, 1946 Patented Nov. 28, 1950 MEANS FOR USE IN APPLYING, ALTERNA- TIVELY, AIR PRESSURE AND SUCTION TO A GIVEN POINT John M. Wyer, Perton, Pattingham, near Wolverhampton, England Application September-30, 1946, Serial No. 700,222 In Great Britain October 3, 1945 3 Claims.
There are many cases where it is required to apply, alternatively, air pressure or suction at a given point, for instance at a chuck used for retaining a utensil thereon or therein by creating suction within the chuck during some operation on the utensil, and then applying air pressure to the'chuck to remove the utensil. The invention has for its object to provide improved means for the above purpose.
The invention comprises a valve constituted by a plug rotatable in an outer shell to which lead two pipes one of which is subjected to air pressure and. the other to suction, the shell being closed at one end and having at its other end a passage leading to the point where the pressure or suction is to be alternatively applied, the shell having also a port communicating with the atmosphere. Ports or passages are formed in the plug and are so arranged that, at one position of. the plug, the pressure pipe is put in communication with the point of application while the suction pipe is put in communication with the atmosphere so that air can flow back along the suction pipe conveniently to feedanair pump; while, at another position of the plug, the suction pipe is put in communication with the point of application and the pressure pipe in communication with the atmosphere, so that only atmospheric pressure may oppose the pump when acting to create the suction.
A convenient embodiment of the invention is described with reference to the accompanying drawings, of which:
Figure 1 is a longitudinal vertical section of the valve and its carrier the section being taken in r the plane indicated by the line i, l, of Figure 2.
Figure 2 is an end view of the valve looking in the direction of the arrow of Figure 1.
Figures 3, i and 5 are transverse sections each taken in the plane indicated by the line 3, t, of Figure 1 and showing different positions of the plug.
In these drawings A indicates the shell of the valve mounted in a carrier P and B is the rotatable plug. The shell has a central passage C leading to the point where the pressure or suction is to be alternatively applied. The other or front end of the shell is closed by a gland D out through which passes a forward portion b of the plug having secured. to its forward end a wheel E by which it is turned.
The shell A has three main ports disclosed at angles of 90 degrees, one of which F is a pressure port communicating by a pipe F with the pressure side of an air pump (not shown), an-
ic disposedat right angles and the chamber M ;tion with the 2 other of which G is a suction port communicating by a pipe G with the suction side of the pump and the third of which H is a port communicating with the atmosphere.
The plug Bis closed at its forward end by a wall I) and it is divided by a longitudinal wall 22 into two chambers K and M, the'chamber K being open at its rear end to the passage C. The chamber M is closed at its rear end by a wall m.
The chamber K has two peripheral ports It,
has two peripheral ports m, m
It will be seen, by reference to Figure 3, that the port k of the chamber K is in communicapressure port cf the shell, the other port is being closed by the body of the shell. Hence pressure is applied through the chamber K to the passage 0. At the same time the port m of the plug is in communication with the suction port G and the port m, in the plug, with the atmospheric port H in the shell so that air can flow freely to the suction side of the pump.
Referring to Figure 4 it will be seen that the port 7c of the chamber K is in communication with the port G of the shell so that suction is applied to the passage 0 through the chamber K. At the same time the port m of the plug is in communication with the pressure port F of the shell allowing pressure air to flow into the chamber M and out therefrom through the port 111. of the plug and the port H of the shell.
Referring to Figure 5 the port k has just commenced to open to the pressure port F but it is also open to an auxiliary port J allowing air to blow out and relieve the point of application of too sudden application of pressure. When the port 70 is fully open to the port F the aux- 'iliary port J becomes closed by the space between the ports k and 7c The degree of opening the port F can be varied at will and at the same time the degree of blow out by the port J. Hence the degree of pressure applied to the passage C can be controlled. A similar action takes place when the port is opening to the suction port G.
It is to be understood that the ports referred to as communicating with the atmosphere may communicate with any region where the pressure is substantially that of the atmosphere.
Having fully described my invention what I claim and desire to secure by Letters Patent is:
