EMERY L. BULKLEY, 0F PAINTED iOS'l, NEW YORK, A$SIGNQR T0 INGEKSQLL-RAMB COMPANY, 03 JERSEY CITY, NEW JERSEY, A CORPORdT-IOIZ 0? NEW J nneuiierros, roe rnuin-conranssons.
To all whom it may concern:
Be it known that I, EMERY L. BULKLEY, a citizen of the United States, residing at Painted Post, in the county of Steuben and State of New York, have invented a certain new and useful Improvement in Regulators for Fluid-Compressors, (Casein) of which the following is a specification.
This invention relates to regulators for fluid compressors; and more particularly to regulators wherein to reduce the load on the compressor the intake of the compressor is closed and the discharge line opened to atmosphere whenever the pressure in the receiver reaches a predetermined amount. It has been proposed in this type of regulating mechanism to operate boththe intake closing valve and the discharge line opening valve simultaneously, by admitting compressed fluid. from a pressure controlled valve to the operating motors of both intake and discharge line valves at the same time. In cases, however, where the compressor is unloaded at frequent intervals there is a considerable waste of energy, in that all the air in the compressor at the time the unloading'valves are operated is pumped through the compressor and out into the atmosphere.
The object of the present invention is to provide means whereby the discharge line unloading valve will not be opened to atmosphere until a short time after the intake valve is closed. This will allow all, or a large portion, of the air in the compressor to pass through the discharge line and to the receiver before the discharge line valve is opened. With this object in View, a regulating mechanism has been devised, a practical embodiment of which is represented in the accompanying drawing, whichshows an elevationof a compressor with the important parts of the regulating mechanism in section.
The compressor, as shown, comprises a low pressure'cylinder 1 and a high pressure cylinder 2 connected by an intercooler In the inlet pipe 4: which leads into the low pressure cylinder is an intake closing valve 5 which closes against a seat 6. The valve 5 is opened or closed by a piston 7 which slides in a cylinder 8. In thedischarge line 9 of the compressor which leads to a. receiver 10 is placed a discharge line unloading valve 11 which controls a port 12 Specification of Letters Iratent.
discharge line 9 is also a check valve 1* which prevents the return of fluid from th when the valve 5 is closed.
f cernber 5th, 1914, I have claimed broadly Patented Jan. 327,
Application filed December 5, 191 Serial No. 875,588.
leading by a pipe/13 to atmosphere. in
receiver 10 when the port 12 is open. '5? discharge line unloading valve 11. and ch. valve is may be of any well known co; struction, but are here shown as disclosed in the. patent to William F. Treiher, 1,093,299 dated. April 14th, 191%. valves 11 and lei are supplied with'opei ing fluid through a pipe 15 of considerable length which opens into the side of cylinder 8 at a point just uncovered. by the piston 2' Fluid is a mitted to the cylinder 8 at a predeterm .i. receiver pressure thron h a. pipe it? a pressure controlled mile mechanism i7, such as shown, for instance, in the applies-- tioh of Castle and Rogers, Seria- 7 91,709 filed September 25th, 1913, this valve 17 being conn cted with the receiver 10 h a pipe 18, this connection not being shown.
In operation, when the pressure in the receiver 10 reaches a predetermined mash mum, the valve 1'? opcratiis to admit timid through the pipe 16 to cylinder 8. This will move the valve 5 upwardly, closing intake of the compressor. After the valve closes, pipe 15 will be open to the pressure in the cylinder 8, but, dueto the length of the pipe 15, the discharge line valve 11 will not open immediately, but will be retarded for perhaps several strokes of the compressor, allowing practically all of the air in the compressor to be passed by check valve lei. into thereceiver before this valve 11 opt In this way very little air which has been already compressed and has hence consumed energy, will be lost. In my co-pending plication, Serial Number 875,589, tiled combination'o f a compressor, its receive a fluid operated discharge line unload valve mechanism, a fluid operated intai closing valve, means for admitting fluid to operate said valves at a predetermined ceiver pressure and means for delaying the action oi s id fluid in operating said dis charge line unloading valve mechanism, ar. the claims in the present application. are directed to a specific modification of the broad idea embodied in the above mentioned application.
v It is to be understood that while the pres-- ent showing and description discloses only H v I mmpm one specified modification of the iiavembion,
' other forms and. modificatiens are included i in the spirit and scope of he same as 625- pressed in the claims.
What 1 claim is:
1. In a, regulator for fluid compressors, in combination, a eorizpressor, its receiver, a (iischa rfie line unloading valve mechanism im me e closing valve, a valve mechanism for operating said intake valve at e, prede termined receive: pressure and means con.-
trolled by the movement of said intake valve 1 ply by the movement of said veying'. fluid to operate said discharge line valve controlled by the movement of said intake closing valve, -60 open said discharge valve after said intake valve has closed.
I; 3. in a regulator for-fluid compressors, in combination, a compressor, its receiver, a discharge line-openmg valve, an intake closing valve, valve mechanism for closing said J intake valve at a predetermined receiver pressui'e,-e piston for operating saiii intake elosing valve, and a fluid conduit eeding to said discharge valve opened toe n'uigi suppiston in' closin said ineake valve.
m testimony whereof, I have hci'eimto set myhand.
