Abstract
ABSTRACT OF THE DISCLOSURE
A faucet has a sealing member clamped at its periphery and overlying an orifice through which fluid is to flow.
Pressure applying means maintains the sealing member in seal-ing engagement with the wall defining the orifice. Upon re-moval of the pressure applying means the sealing member moves away from the orifice to permit flow.
The pressure applying means is located n a valve body which is screwed into the faucet housing and acts to change the periphery of the sealing member. The valve body may be removed by removing the handle and engaging a pair of projections within the handle with a pair of ears on the valve body. The sealing member is thus unclamped and easily removed.

Description
3 096~44 This is a divisiollal application of Canadian patent application serial number 321,141 filed on February 7, 1979.
This invention relates to devices for controlling liquid flow and in particular to faucets for domestic installations.
It is o~ course known to provide a faucet with a valve to control ~low of water into a basin or similar receptical.
The valve members associated with the faucet is usually operated by rotation of a spindle which moves a seal toward and away from a seat~
The seat is usually carried by the spindle and is formed from an elastomeric material such a rubber. The splndle is located within a valve housing and projects therethrough for connection to a suitable handle. It is therefore necessary to provide suitable seals between the spindle and the valve housing.
Since the seal is carried on the spindle it is subject to both torsional and compressive strains as it is brought into contact with the associated seat. This subjects the seal to relatively rapid wear which causes leaking of the faucet. This causes the faucet to drip which results in an appreciable increase in energy consumption, particularly where the faucet is controlling a heated water supply, as well as being a source of aggravation for the householder.
It is therefore necessary on a reasonably frequent basis to change the seal member.
This operation has traditionally required the use of skilled assistance which is naturally very expensive. Even where the householder possesses the knowledge required to change the seal himself it is necessary for him to possess the correct tools to disassemble the faucet. The valve housing of the faucet is usually assembled by means of a large nut which means - 1 - ~L
that the average householder d~es not have a spanner suitable for disassembly. The replacement of the seal member which may itself only costs a few cents therefore requires the use of skilled labour resulting which becomes expensive. This pro-blem is compounded in large commercial organizations such as large hotels which utilize many hundreds of taps.
It is an object of the present invention to obviate or mitigate the above disadvantages.
According to the present invention there is provided a faucet for controlling liquid flow comprising a housing, wall means in the housing defining an orifice through which liquid is to flow, a substantially flat sealing member having one face overlying the orifice, a support surface for the periphery of the sealiny member, the surface being provided by a radially inwardly extending flange coaxial with the orifice, clamping means for holding the periphery of the sealing member into seal-ing contact with the support surface, pressure applying means selectively operable to apply pressure to the other face of the sealing member to orce the one face into sealing contact with the orifice, and a handle adapted to operate the pressure apply-ing means the pressure applying means including a piston slid-ably mounted in the housing and having guide means co-operating with the housing to prevent rotation of the piston relative to ; ~ the housing and a spindle rotatably mounted in the housing and ~ connected to the handle for rotational movement therewith, the -~ ~ spindle having a threaded portion engaging a complementary threaded portion provided on the piston whereby rotation of the spindle by the handle induces ~liding movement of the piston : ;: . ~ .

The sealing force is imparted to the sealing mem-ber by the non-rotatable piston in order to avoid subject-ing the sealing members to torsional loads.
The handle may be detached and is preferably provided with a pair of inwardly directed projections which engage in suitable holes in the valve housing. This enables the handle to be used as a tool to disassemble the valve hous-ing and permit change of the seal.
Embodiments of the present invention as well ~s those of ~he parent application will now be described by way of example only with reference to the accompanying drawings, in which:-Figure 1 is a cross-sectional elevation through a faucet in an assembled and sealing position;
Figure 2 is a sectional elevation similar to that shown in Fig~re 1 with the compcnents arranged to assist in disassembly of the faucet;
Figure 3 is a view on the line III-III of Figure l;
and Figure 4 is a scr~p view oi a portion of a further embodiment of a faucet showing alternative positions of the components thereof on opposite sides of the Figure.
Referring now to Figure 1 a faucet generally desig-nated 10 includes a body 12. The body 12 comprises a tubu-lar threaded portion 14 which depends from a valve cavity 16.
The valve cavity opens into a spout portion 18 having a suit-able discharge nozzle 20.
A valve seat 2~ i~ screwed into the valve cavity 16 through screw threaded portion 14. The valve seat 22 is of frusto-conical shape which terminates in an annular wall 25 to define an orifice 24.
A check valve 23 is located within the valve seat 22 and is biased by a light spring (not shown) into a sealing position with the valve seat 22. A spigot 21 is provided on the check valve 23 and extends upwardly into abutment with a sealing member 36 so that the check valve 23 is normally held open.
An aperture 26 is formed at the opposite side of the valve cavity 16 to the threaded portion 14 to receive a seal support housing 28. The seal support housing 28 comprises a cylindrical body portion 30 and a radially inwardly extending flange 32.
The flange 32 encompasses the upper portion of the valve seat 22 so that the orifice 24 lies in the same plane as an upper surface 34 of the flange 32.
Flat sealing member 36 is supported on the upper surface 34 so as to overlie the orifice 24. The sealing member is preferably made from an elastomeric material although any suitable flexible material may be used.
An internal surface 38 of the body portion 30 is threaded to receive a valve assembly 40O The assembly 40 has a valve body 42 which is defined by upper and lower interconnected cylindrical portions 44, 46 respectively. The lower portion 46 has a thread formed in the outer surface thereof to cooperate with the threaded surface 38 of the body portion 30. The lower portion 46 terminates in annular surface 48 which engages an upper surface of the seal member 36 and is aligned with the surface 34 of the flange 32. The seal member 36 is therefore clamped between the surfaces 34 and 48 so that rotation thereof is avoided.
The upper portion 44 is closed by a partition 50 with a throughbore 52. The partition 50 extends to either side of the upper portion 44 to form a pair of diametrically opposed ears 54, 56, as can best be seen in Figure 3. ~ach ear 54, 56 has a throughbore 58, 60, respectively.
~ ~ Q ~ 4 ~
A spindle 62 extends throu~h the throughbore 52 and is rotatably securea therein by a circlip 63. The spindle 62 has a large pitch thread 66 Eormed at one end which extends toward the sealing member 36. A piston 68 has a mating internal thread-ed surface 70 and is slidingly received within a closed bore 72 in the upper body portion 46. As can best be seen in Figure 3, the piston 68 and bore 72 have a hexagonal cross-section so that rotation of the piston 68 is pre~ented.
The piston 68 has a planar end surface 74 which engages the upper surface of the seal member and overlies the orifice 24.
The opposite end of the spindle 62 to the thread 66 has a series of flats 64 formed thereon. The flats 64 engage in a socket 76 which is integrally formed with a handle 78. The handle 78 has a peripheral wall 80 which extends downwardly toward the up~er surface of the seal support housing 28. The inner surface 81 of the wall 80 has a pair of integrally formed inwardly extending projections 82, 84 thereon, The projections are formed with a radially extending arm 88 and an axially extending arm 90. The pitch circle diameter of the axially extending arms 90 is the same as the pitch circle diameter of the throughbores 58, 60. The flats 64 are arranged so that with the valve assembly in a clofied position the projections 82, 84 are circumferentially displaced from the ears 54, 56 as shown in Figure 3.
The operation of the device is as follows:
The threaded portion 14 is connected to the normal domes.
tic water supply so that fluid under pressure is delivered to the interior of the valve seat 22. The spigot 21 is in abut-ment with the sealing member 36 so that the check valve 23 is held off its seat. The end surface 74 of the piston 68 forcesthe sealing member into contact with the annular surface 25 of the valve seat so that flow through the orifice 24 is prevent~ -ed. It will be observed that in this position the piston end surface 74 extends across the orifice 24 so that the sealing member is only subject to compressive forces in a closed position.
To open the faucet and permit fluid to flow through the orifice and into the spout 18, the handle 78 is turned clock-wise which causes the spindle 62 to rotate clockwise. Since the piston 68 is held against rotation the threads 66 and 70 will co-operate to cause the piston to move axially along the bore 72. The piston end surface 74 is thus moved away from the upper surface of the sealing member 36 whIch allows the sealing member to flex. Fluid pressure therefore moves the sealing member 36 away from the annular surface 25 and permits flow into the spout 18. The spigot 21 still holds the check valve 23 away from its seat since movement of the seal member 36 is insufficient to permit seating.
To close the faucet the handle 78 is rotated anti-clockwise to move the piston 68 back into the sealing position. It will be noted that the sealing member is not subjected to torsional rotation during opening and closing of the valve since the pis-ton 68 is non-rotatable and the periphery of the sealing member is firmly held between the surfaces 34 and 48.
It will also be noted tHat the sealing member 36 partitions the valve assembly from the fluid~ This enables the faucet to be assembled without additional sealing arrangement around the spindle 62 and improves the fluid tightness of the faucet.
In order to renew the sealing member or to disassemble the faucet, thehandle 78is firstremoved by pulling axially upwards.
-6~
l~q6~44 The flats 64 thus are disengaged from the socket 76 and the handle 78 can be removed. The handle 78 is then positioned in the manner shown in Figure 2 with the axially extending arm 90 engaged in each of the bores 58, 60. The handle 78 can then be twisted to unscrew the valve assembly 40 from the sealing member support housing 28. As the valve assembly is removed the fluid pressure acting on the sealing member 36 forces it away from the upper surface 34 of the flange 32. This permits the check valve 23 to seat within the valve seat 22 and prevent flow of fluid through the orifice 24, The sealing member 36 may then be readily removed and a new sealing member inserted.
The valve assembly 40 may then be screwed into the seal support housing by using the handle 78 which may then be re-assembled on the spindle 62.
The relative axial positions of the projections 82, 84 and the ears 54, 56 permits full rotation of the handle to accom-plish full opening of the f~ucet. It will be seen therefore that the arrangemen~ disclosed herein permits assembly and dis-assembly of the faucet witho~lt the need ~or special tools or skilled labour.
Figure 4 shows a further arrangement of handle and valve assembly in which pins 110 are located on the upper body portion 44. A ring 112 is secured w~thin the peripheral wall 80. The ring 112 has a pair of diametrically opposed grooves 114, 116 which are dimensioned to pass over the pins 110. As can be seen from the left hand side of Figure 4, when the socket is located on the flats the ring 112 is below the pins 110 to per-mit rotation of the handle. Upon remov~l o~ the handle from ; the spindle, the pins 110 m~y be pos2tl0ned in the grooves 114, 116, as shown in the right hand side of Figure 4 to permit disassen~ly of the fducet.
The arrangement shown in Figure 4 may be constructed so that it is no~ necessary to completely detach the handle. The handle may be attached to provide limited axial movement to enable the pins to engage the grooves in the manner of a bay-onet fastening.
Further the check valve 23 may be made buoyant and a transverse wire provided to retain the check valve within the threaded portion. A groove may be provided to assist in location of the check valve i~ desired, It will of course be evident that the partIcular arrange-ment of sealing member can ~e used independently of the arrange-ment of the handle, However, ~y combrning the two arrangements the use of sealant to secure the valve assem~ly within the body is not required since the ~al~e assembly is not exposed to fluid. This enables the torque required to assemble and disassemble the body to be reduced, The danger of the valve assembly becoming corroded into the body is also reduced, It will also be appreciated that other types of valve operating mechanisms can be utilized other than rotary members, such as cams and levers.
Also it is not essent~al for the sealing member to be formed from a flexible material, The central position of the sealing member could be ri~i~d with the peripheral portions formed with flexible material~ Alternatively~ surfaces 34, 48 could be axially spaced so that the sealing member could float between open and closed positions. With such an arrange-ment however, the likelihood o~ leakage ~nd premature wear ~ may be increased.
