Definitions

  • a reversing cock for distributing water under pressure in which a dispensing nozzle having an outlet orifice and a union adapted to be connected to a shower pipe branch off from the cock body forming a water receiving chamber to which ingress of water is controlled by a conventional valve, and in which a valve arranged in the outlet orifice of the nozzle is normally held in open position spaced from a registering valve seat in the orifice by a spring and provided with an outer gripping collar fixed thereto to be moved against the spring force to a closed position in which it is then held by the water pressure.
  • another valve normally seated by Spring means but adapted to open under predetermined pressure is provided in the union.
  • This invention relates to reversing cocks designed for distributing water either to a shower nozzle or to a bath.
  • this invention is concerned with reversing cocks of the type wherein the cock body comprises on either side of the water-receiving chamber on the one hand a bent dispensing nose disposed at the lower portion and provided at its lower end with a downwardly directed outlet nozzle, and on the other hand at the upper end of said chamber a union for connecting the cock to a shower pipe or the like.
  • the main valve of these cocks controls the ingress of water into the receiving chamber.
  • another, manuallyoperated valve adapted to prevent the delivery of water through the outlet nozzle is provided.
  • This other valve is normally urged to its open position by a spring so that when the main valve of the cock is opened by the user the water will flow as usual through the outlet nozzle. This is due to the fact that the water will flow more easily through the outlet nozzle than towards the upwardly directed shower pipe union.
  • devices of this type are objectionable in that they require the provision of some internal bafile means so that in the duct leading to the normal outlet nozzle and therefore to the bath the water be properly directed towards the seat of the stop valve in order automatically to hold this valve in its seated position after it has been manually moved thereto.
  • this internal baffie obviously constitutes a complication in the manufacture of the cock body and increases the cost of the device.
  • a reversing cock for distributing water which comprises, on either side of the water receiving chamber, a downwardly directed outlet nozzle disposed at the lower portion of the cock body and a union or like connecting member disposed at the upper portion of the cock body for connecting same to a shower or like pipe, a valve adapted to be actuated by means of a control member being provided for stopping the flow of water towards the outlet nozzle, on the bath side,
  • this reversing cock being characterized in that said valve is movable in the lower end of said outlet nozzle and adapted to co-act with a valve seat registering with the outlet orific or passage of said outlet nozzle, said valve being normally urged away from its seat by spring means
  • the valve control member consisting of a cylindrical core mounted on a vertical shank rigid with said valve so as to constitute its control and guide member, said core being advantageously disposed at the lower portion of the outlet passage of the nozzle.
  • valve member normally seated by spring means but adapted to open under a pre determined pressure is advantageously provided in the union for connecting the shower pipe to the cock.
  • the valve due to the specific mounting of the valve at the end of the outlet nozzle and also to the specific arrangement of this valve, the latter is automatically urged to its closed position by the water pressure without requiring the provision of any additional bafile means within the cock body.
  • the presence of a springurged valve member in the outlet union on the shower side will eliminate any risk of back flow on this side when the valve on the bath is open.
  • the member controlling the stop valve mounted in the outlet nozzle consists of a socket mounted in the outlet passage of this nozzle and rigid with a central core secured to the end of the valve shank, the lower end of this socket carrying gripping collar projecting radially from the outer wall of the outlet nozzle.
  • a cylindrical chamber open at its lower end and adapted to house the valve in the open position thereof.
  • the purpose of this chamber is to prevent an abnormally high water pressure from acting upon the valve during the closing movement thereof, and therefore from causing a too fierce closing or seating of this valve.
  • FIGURE 1 is a vertical section showing a reversing cock constructed according to the teachings of this invention
  • FIGURE 2 is a fragmentary view showing on a larger scale the outlet nozzle of the cock with the valve in its normal open position;
  • FIGURE 3 is a view similar to FIGURE 2 but showing the valve in its closed position
  • FIGURE 4 is a cross-sectional view taken upon the line IVIV of FIGURE 2;
  • FIGURE is an axial section showing the socket constituting the valve control member
  • FIGURE 6 is a plane view from above of the same socket.
  • the cock illustrated comprises a main body 1 in which a water-receiving chamber 2 is formed. Mounted in this chamber is a conventional valve member 3 the movements of which are controlled by a screw rod-4 carrying a knob 5. This valve member registers with a seat 6 surrounding the orifice of the water inlet duct 7.
  • thischamber 2 On eitherside of thischamber 2 are provided on the one hand a dispensing nozzle 8 at the lower portion of.
  • This valve consists of a diskof rubber or like material suitable for this.
  • this disk being clamped between a pair of metal washers 13 and 14, this valve assembly being secured by a screw to the upper end of a control rod or valve shank 16.
  • This shank extends substantially vertically within, and is coaxial with, the nozzle insert 10. Besides, this shank is mounted for axial slidingmotion in a cylindrcal core or socket 17 disposed centrally of the nozzle insert and fastened through a number, for example three, of radial vanes 18 as shown in FIGURE 4, to the insert 10; a coil compression spring 19 surrounds the shank 16 and is fitted between a shoulder 20- of this shank and an inner flange provided at the lower end of said core 17.
  • the spring 19 constantly urges the controlshank 16 upwards, so that the valve 11 rigid therewith is normally unseated.
  • the valve control member consists of a substantially cylindrical socket 21 mounted inside the nozzle insert 10.
  • this socket 21 is provided with an integral gripping collar 22 projecting radially from the outer wall .of' this socket.
  • the socket 21 carries a central boss 23 connected through radial vanes 24 to the cylindrical wall of the socket, these radial vanes being for example three in number, as shown in FIGURE 4.
  • This central boss .23 has an axial hole formed therethrough which is engaged by the lower end of the. valve the central core 17 to the cylindrical body of insert 10 i (see FIGURES 3 and 4). At the-same time, this arrangement will guide the socket 21 during its vertical movements while preventing this socket from rotating about itsaxis.
  • the inner face of the upper wall of the dispensing nozzle comprises a substantially cylindrical chamber 27 open at the bottom towards the outlet nozzle insert 10.
  • This chamber 27 is adapted to house the valve member '11 when the latter is in its open position (see FIGURE 2). By construction, a very small clearance is left in this valve position between the wall of chamber 27 and the valve member 11: or the washer 14 holding this valve member.
  • valve 28 is provided within the union 9 for connecting the cock to a shower pipe-This valve is normally closed by engagement of a seat 29 under the pressure of a spring 30 counteracting theforce exerted, by the water pressure on this valve. This spring reacts against a nut 31 screwed in the union 8 and formed with a central hole permitting the passage of water when the valve28 is open.
  • valve 28 The purposeof this valve 28is to compensate. the.
  • the cock according to this invention operates as follows:
  • valve 11 When this valve 11 is seated the user can safely release the control socket 21 since the water pressure is now sufiicient to hold the valve in this position. But now, due to this valve closing, the water tends to flow towards the union 9 and the shower pipe by unseating the valve 28.
  • chamber 27 will prevent an abnormally high 'water pressure .from being: applied to the valve 11 during its;closing movement.
  • a condition of balance obtains'between the pressure prevailing above the valve and that prevailing under this valve, since a communication between these two zones is pro .vided by the clearance existing between the valve member and the wall of chamber 27.
  • this pressure is relatively low'since the water'fiow takes place in the free atmosphere.
  • this pressure may be for example of the order of2 p.s.i. grams/ sq. cm.).
  • this valve is subjected to a relatively high force equal to the product of the surface area of this valve by the value of the high pressure prevailing on the shower outlet side, this pressure being for example ofthe order of 14 to 22 p.s.i. Therefore,'if the valve 11 were not housed within the chamber 27 during the-initial part of its closing movement, it would be subjected to a considerable and fierce-pressure variation, so that its closing movement would beattended by a severe shock.
  • valve-receiving chamber 27 In fact, due to the small clearance existing between the valve 11 and the chamber 27, no suflicient time is available for allowing the increasing pressurebuilt .up in the cock dispensing nozzle during the valve closing movement to spread to .the bottom 'of this chamber 27. Thus, the. pressure prevailing above the valve will remainconsiderably lower as long as the valve is not completely closed.
  • valve 11 in chamber 27 constitutes a particularly advantageous improvement since it prevents a too fierce closing of this valve.
  • the reversing cock according to the present invention is advantageous in that it is not necessary to provide any additional baffle means within the dock body or the outlet nozzle. This obviously constitutes a substantial simplification in the cock structure and therefore a reduction in its cost.
  • the member controlling the outlet nozzle valve is advantageous in that it is extremely sturdy and that its presence does not impair the appearance of the cock as a whole. Moreover, the mounting of this control member is not attended by any leakage problem since it is located at the outlet end of the nozzle.
  • a reversing cock for distributing water under pressure comprising, in combination, .a cock body forming a water receiving chamber having an inlet opening; a dispensing nozzle having an outlet orifice at one end and communicating at the other end with said water receiving chamber; .a union connected to said cock bodies spaced from the other end of said nozzle for connecting said cock to a shower pipe; a conventional valve in said receiving chamber for controlling ingress of pressure Water through said inlet opening; a valve movably mounted in the end portion of said nozzle forming said outlet orifice; a valve seat registering with said valve and aligned with said outlet orifice; spring means urging said valve to its open position spaced from said valve seat; a shank fixed to and projecting from said valve into said outlet orifice of said nozzle; a valve control member arranged in said outlet orifice of said nozzle and comprising a cylindrical core secured to said shank and a socket about said core and fixed thereto, said socket having at an outer end thereof a gripping
