HYDRAULIC RELAY FOR REGULATING APPARATUS.
`Application led June 9, 1927, Serial No.
Myinvention relates to a hydraulic relay for regulating apparatus.
Vhen hydraulic relays are employed `for regulating apparatus in which the current of the oil under pressure is controlled by a piston slide with controlling edges a peculiar phenomenon may be observed. By the stream and the formationv of eddies connected therewith additional forces are de veloped which oppose the displacement of the piston slide and which may become of such magnitude that the regulating motion is braked to a complete standstill. This phenomenon is the more serious, as in the control gear mentioned apparatus is used on which the highest demands are made in regard to accuracy of operation. If it is desired to avoid the detrimental additional forces which result from hydraulic phenomena, a control gear must be used in which no reciprocating piston slide with controlling edges is employed. In order to attain vthis end in view I usea tubular member designed in the manner of'a rotary slidev to which an angular rotation is imparted by the regulating impulse. The rotary slide is located in an inflowing stream of oil and possesses two laterally adjoining chambers.
`With the two chambers communicate lines which conduct the quantityv of oil arriving there each to one side of a piston-like member (control piston, diaphragm or the like). The division of the current of oil is eiected in such a wary that the rotary slide which is divided into two separate compartments is so turned that the admission opening of the one compartment is enlarged and that of the other compartment reduced. It will be understood that another liquid than oil may be employed. The drawings aiiixed hereto illustrate an embodiment of my invention as applied to the control of steam by a pressure impulse.
. These drawings represent in:
Fig. 1 a sectional elevation of the hydraulic relay, v
Fig. 2, an axial longitudinal section with a regulating impulsedevice, a control piston and a controlled valve,
Fig. 3, a section along line A--B, and
Fig. 4, a section' along line C-D both in Figure 1 through the hydraulic relay.
Referring to the drawing, 1 is a diaphragm, which seals a chamber formed by a hood 197,756, and in` Germany June 10, 1926.
or in any other manner. To the diaphragm 1s iXed a jointed rod 2 which with its other end engages a rotary tube 3. The rotary tube 3 1s located within a housing 4 and is secured in position in the axial directionby two tubular centers 5 and 6. In the rotary tube 3 are' located two transverse radially extending walls 13 and 14 and a transverse axially extending thin wall 17, connecting the inner ends of walls '13 and 14. By these walls the rotary tube is divided into two compartments 15 and 16.. To the centers- 5 and 6 are 'joined thepipes. 7 and 8 which open into a cylinder 10 at opposite sides of a piston 9.
The motion of the piston 9 is by means of a piston rod v20 and a bell-crank lever 21 transmitted to a valve disc 23. By the ad- ]ustment of the valve disc 23 the passage opening of the regulating valve 22 is enlarged or reduced and the steam flowing in' the direction of the arrow controlled correL spondingly. The chamber behind the regulating) valve is in communication with the cham er 25 above the diaphragm 1 by the pipe Fig. 3 of the drawing shows the arrangement and attachment of the jointed rod 2 at the rotary tube 3 by'means of pins and eyes upon the tube.
Fig. 4 shows a section through the hydraulic relay'along the line C-D. 3 is the rotary tube, 4 the housing, which is provided' with transverse bores 11 and 12. In the rotary tube 3 is furthermore arranged a thin wall 17 in such a manner that in the middle position of the rotary tube it is alined with the axis of the bores 11 and 12. The bores 11 and 12 are connected by a pipe line 27 with a pump 26.
The manner of operation of my improved hydraulic relay is as follows: For instance,
in case of controlling steam the steam entering the chamber 25 sealed by the diaphragm exerts a pressure upon the diaphragm and del'ects it downwards to a greater or lesser extent. The jointed rod 2 then adjusts the rotary tube 3 and the thin wall 17 accordingly. Assuming that the rotary .valve 3 has turned counter-clockwise into the position shown in dotted lines in Fig. 4. The pipe 11 is then y in unrestricted communication with the compartment 15 of the rotary slide valve,'while the other compartment 1 6 is cut o if from the ter pin 6, the compartment 16 'and the bore 12 back to the pump 26. By the piston S) and by means of the piston rod 20 and .the hell- Crank lever 21 the valve disc 23 in the steam control valve 22 is moved downwards and thc valve opening correspondingly reduced so that a smaller volume of steam passes through the valve opening. The pressure behind the valve consequently drops and correspondingly also in the chamber 25 above the diaphragm. The diaphragm thus takes up a new position. Vhen a regulatingmotion takes place in the opposite direction the flow of the pressure oil into the chamber 15 is reduced and the flow into the chamber 16 increased, whereby the piston is moved in the opposite direction. The circulation of the oil`- entering the bore 11 and issuing from the bore 12 is maintained preferably by a rotary pump 26. v l
The regulating impulse shown as pressure impulse may equally well be designed as temperature impulse, quantity impulse or the like.
My improved relay is suitable for all kinds of regulating purposes, for instance for the regulation of steam generators, the pressure regulation of power p ants, for heating plants in the chemical industry and so on.
Various changes and modifications may be made in my invention without departing from its spirit and I desire, therefore, that only such limitations may be placed thereon as are imposed by the prior art.
I claim as my invention z- 1. A hydraulic relay for controlling servomotors or the like by a controlling force7 coinprising means for circulating anoperating liquicha relay housing and a tubular element rotatably disposed therein and operated byv the controllinfY force, hollow trunnions for holding said elment endwise in place and for conducting the operating liquid circulating between the servomotor and the relay, a suitably shaped transverse partition in said element dividing its interior into two compartment-s and ports in said element and said housing adjacent to said partition, and pressure liquid supply means connected to said ports, said partition dividing the stream ot supplied liquid between said compartments in accordance with the angular position assumed by said rotary element to operate the servomotor by the pressure diiierence between the two divided streams..
