Title: Improvements in or relating to automatic air compressors
IPC: F04B31/00
Filed: 1922-07-29
Abstract: 183,849. Babin, J. July 30, 1921, [Convention late]. Regulating.-An air-compressor comprises an internal-combustion motor cylinder, a compression cylinder, and a reservoir into which the air is discharged; the motor and ccmpressor pistons are rigidly connected together and without mechanical transmission means, and may be of wood or other light material. Air from the reservoir passes through a regulating-device either to the motor cylinder or to be used externally. The apparatus shown comprises three coaxial cylinders 1, 2, 3 containing free pistons 4, 5, 6 rigidly united, and is mounted upon a reservoir 7. Combustion takes place in the cylinder 1, which is provided with mechanical inlet and outlet valves; compression occurs in the cylinder 2, which is of larger section, air and water entering by a valve 15 and being discharged through a pipe 17 into the reservoir, apertures 18 in the lower part of the cylinder 2 allowing free communication with the atmosphere; the compressed air enters the cylinder 3 from the reservoir and effects the return stroke, which is completed by the momentum of the pistons. The air passes from the reservoir into a pipe 40 having outlets 41, 43 by which it flows either through a passage 42 for external utilization or through a pipe 44 to the carburettor 46 of the motor, heated by the exhaust gases. The outlets 41, 43 are controlled by a slide valve depressed by a spring 34 and raised by water forced up a pipe 36; the valve is formed with grooves 28 - - 31 so disposed that the outlet 41 is closed and the outlet 43 fully open in the lowest position of the valve, while, when the valve is in the mid-position, the outlet 41 is fully open and the outlet 43 partly closed; as the valve rises, the outlet 41 remains fully open while the outlet 43 is gradually closed. The lower end of the cylinder 3 serves as a dash-pot and is formed with a small orifice 26. A series of compressors may be mounted in stages, the cylinder 2 of a high-pressure stage being enclosed in a casing surrounding the apertures 18 and inlet valve 15; in compound working, the air compressed at any stage may supply the motor of another stage, and the air may be delivered into a reservoir of another stage. The engine may be worked by gas, a portion of the compressed air being bypassed through a closed gas-producer. When a gas is to be compressed, the air supply for the motor is derived from a separate compressor.

Abstract: 1,145,087. Hydraulic apparatus for controlling mine roof supports. BONSER ENG. Ltd. May 19, 1966 [May 19, 1965], No.21110/65. Heading F1P. A supply of pressurized fluid P1 is passed to a two-positioned selector valve 2 through a valve 1, of the type described in Specification 1,123, 831 (see Division F2), the valve 1 being adapted to provide a different output pressure in a line 5 depending on the position of the selector valve 2. The selector valve 2 may be connected by a line 7 to the extension chamber 3 of a mine roof support 15 and by a line 9 to the retraction chamber 4 thereof. To extend the support the selector valve is set to connect line 7 to the output line 5 so that pressure fluid flows through ports 13 in the valve 1, displaces a valve member 17 against a spring 19, and passes through the lines 5, 7 to the chamber 3. As the pressure builds up in the line 5 it acts on the surface 16 of the valve member 17 to close the valve and hence establish in the chamber 3 a pressure lower than the supply pressure P1. When the selector valve is changed over to pressurize the chamber 4 an annular chamber 20 of the valve 1 is also pressurized and the pressure acts to increase the pressure at which the valve 1 closes to that of e.g. the supply pressure P1.
