The present invention is an improved control valve and is an-improvement on a device Letters Patent of the United States, Number 1,474,164, issued to me on 5 November 13th, 1923.
The objects of this invention include y provision oi a controlval've, for
shown in (i) The applied to work,
bore as avunit.
(3) A control valve parts are mounted between resilient members lin lioating relation whereby the parts are iree to accommodate themselves to their reo-acting parts, thus providing ak permissible limit of range and avoiding necessity of adjustment.
ln this specication and the annexed the invention is illustrated in the form considered to be the best, but it is to be understood that the invention isnot limited' to such form because it may be embodied in other forms," and it is also to be understood Athat in and 4by the claims 'following the description it is desired tojcover the invention `in whatever form-it may be embodied.
- In the accompanying drawing, Figure l is a vertical central cross-section ot' my ins'pective seats or c drawings,
vention, and
Fig. 2 is a. section ot' Fige 1 takeuon line Il-llf.
Referring to the drawing the numerals indicate the respective parts I, y
At 69, l show a bore which is areduced portion of a bore 71 in a valve casting 70. The bore 7l is threadedto engage a plug 85. At 68, I show a discharge port through which liquid passes-to a workline and at 72 l show an intake passage through which liquid under pressure is admitted to bore from a pressure tankl.
CONTROL VALVE.
` Application filed February?, 1924. Serial No. 691,223.
wherein liquid in which the moving seat 75. The
a piston 94.
Stretch of said spring plunger 83.` Valve 86 The function of the control valve is to admit liquid under pressure Jfrom tank 31 past a valve seated at 7 3 to a brake line connected 'to outlet 68, and underconditions release said liquid from said brake line by return through passage 68, thence past a valve seated at 75, through a port 7 4, to the source 55 of supply, thus completing the liquid circuit.
The control valve is manipulated to admit liquid pressure from tank 31 to the brake line vbya pull rod 76 connected at one end to a foot pedal,y hand lever or the like, and at the opposite end to one end of an elbow lever 78 pivoted at 79 in a bracket 8l on the kcasting 70. The end 82 of the elbow lever 78 remote from spring 77 is designed to depress a plunger 83 Slidable in bore 69. This plunger is centrally bored to form a passage 84 coinmunicatingwith a port 74 and the lower end of saidfbore forming the valve downward ymovement ot plunger 83 iscommunicated to a valve 86 secured vto a stem 87 integral with a' valve 88, which last named valve is thus unseated.
The unseating of this valve releases liquid romva chamber 89 faster than it can be replaced through a passage 91 which connect with passage 72 through flutedpassages- 92 and ports 98, thus 'releasing pressure behind Thecross-sectional area o-piston 94 is greater than that of the seat 7 3, therefore the valve will beforced from its seat by pressure at 72, and liquid will pass seat 73,
the brake line, until pressure in the brake line rises to a'degree at which the pressure on theinner end of vthe plunger 83, transmitted through elbow leverl 78, will overcomethe urge of spring 77.
When the Spring 77 is thusovercome, the
permits the rise of .follows the plunger seat 7 5 by pressure, 'and also bya spring 96, As thevstem 87 of valveA 88 is connected to valve 86, it will rise at the same time and' seat, preventing'further passage of'liquid lfrom chamber 89.v
jPresSure is promptly accumulated .in
1XvVhen so balanced this piston 94, urged by a spring 97 and the ilow of liquid at 7i, seats and closes conimunication between pressure tank andthe brake line connected to passage 68. So long as the tension on spring 77 remainsunchanged, the pressure in the brakev brake line acting on the lower end oit said plunger 83 lifts it and unseats valve 8o (because valve 88 serves asia stop` limiting the 'upward movement o1 valve 80,) releasing liquid from the brake line through passage 841- and port 74 to a chamber 80 connected to the source of supply. This release takes place, however, only until such time as the pressure in the brake line (acting on the vbottoni olf plunger 83) balances with the remaining tension on spring 77. Ity will be seen that the release of pressurel on 'the brakes will be directly proportionate to the releasing movement oit the foot pedal by the driver.'
The saine is true when brakes are applied. A forward pull on rod 7 6 increases tension of springs'77 and brakes will be applied until pressure in the line balances` said tcnsion, the degree of said application being directly proportionate to the travel ot the foot pedal.
This makes my invention adaptable to conventional automobile controls, as the, action, re-action and resistance correspond to that produced by mechanical means.
The valve 88 is also provided with a similar iluted guide 99 for the opposite end of the valve stem.
.It will be seen that the piston 9&1- moves (to seat or unseat valve at 73) depends on the Aproportionate oros.; sectional area ol the bore 91 and of a bore 100 in saidpisto'n.
vAssun'iing that a sudden brake application to be made, a sudden pull on rod 76 will depress arm 8:2 of the elbow lever, and this depresseslplunger S3, valvevSG (in Contact therewith), forcing pinV 101 into bore 91,
'thereby greatly diminishing the area of said bore. The downward movement of the valve stem unseats valve 88, opening passage 1.00.y 'At this time, pressure at 72 torces piston 94 downward and liquid is displaced quickly Vbehind said piston through passage 100.
As the" length of pin 101 to keep passage 91 closed returns to its seat, it will be pressure in the brake line equalizes with the tension of spring 77, the fulll area ot passage 91 will be effective to causey a sudden is not sufiicient when valve 88 lrise of piston 9a to seat 73.
I prefer to 'form passage 91 in a. separate member 102 threaded into plug 85.vr At 103, in said member, I show a screwv driver slot, wiiich also serves to prevent a closekof'communication between passage 91 and chamber 8 9 when the piston 9d abuts the member 102. This prevents any possibility of fluid lock.
Ity will be seen that all the moving parts may be withdrawn from the valve casting 70 by removing plug 8:5 and a.v plug 1011. The plug 1041 serves as a stop for engaging a shoulder 10G on plunger S'laud limiting the upward movenieiit'thereof. Y
I claim: f r
1. A control valve comprising inlet and discharge chambers, said chambers lconnected by a passage, aA main valve adapted to control said passage, said valve mounted on and moved by a piston, an auniliary valve adapted to control a channel from ,theidis charge to al space behind said piston, a subsidiary valve mounted in the piston and adapted to control a waste 4from the discharge, said subsidiary valve adaptedby its movement to operate said auxiliary valve,
all of said valves being so arranged in said passage that they may be .withdrawn from one end ofsaid passage as a unit.
2. A control valve comprising inlet and discharge chambers, said chambers connected by passage, a main valve adapted to control said passage, said valve mounted on and moved by a piston, an negrilla-ry valve seen that, when adapted to Control a channel from the eliseharge to a space behmfl salcl vplston, a subslcllary valve mounted m the plsten and `adapted to control a Waste 'from the discharge, said subsidiary valve adapted by its movement to operate slalcl auxlllary valve, and Saul auxlllary valve adapted to serve as a stop for limiting the travel of said subsidiary valve, all of sacl valves being so arranged n said passage that they may be 10 Withdrawn from one end of said passage as a unit.
In testimony whereof I affix my signature.
