摘要:
A faucet assembly includes a housing that defines a cavity. Within the cavity there is a ball valve that is held in place by cam surfaces of a cam. The cam surfaces positively and directly contact the ball valve without a pliable seal member disposed there between. The possible location of the ball valve eliminates linear movement. Further, a seal assembly is disposed between the cam and the ball valve in locations that are not in direct contact with the cam surfaces. The cam surfaces hold the ball valve in place separately from the seal resulting in less load on the seal to provide lengthened seal life.

An improved ball valve mechanism requiring no handle for the direction and intermixing of two or more liquids. Control of liquid volume, admixing and directional output is accomplished by manipulating the spout itself which acts both as the liquid outlet and the controller. A swivel spray aerator fixture can be used to redirect the flow to any location in the sink. The configuration of the ball valve mechanism is hollow and has a hollow stem through which the admixed liquid is directed into the spout. Pins are provided in the ball valve body which engage slots in the ball valve mechanism enabling more precise control over rotation of the ball valve mechanism.

A single handle ball valve faucet (10) having a ball valve element (24) mounted in the housing (12) such that the handle lever (82) is moved to a rearward and up position to place the ball valve in an off position and to an easily accessible forward and down position to place the ball valve element (24) to an on position. A control plate (50) has a control opening (70) with a rearward facing apex 72 for receiving the control stem (80) of the ball valve when in the off condition and a wide forward edge (74) for allowing lateral motion of the stem (20) therealong for adjusting temperature mix of the water when the ball valve element (24) in the full flow on condition.

A mixing valve for a faucet has a ball valve (16) mounted for pivotable motion about a longitudinal axis (76) and a second perpendicular axis (86) that is fixed with respect to the pin (84) that extends through the spherical section (42) of the ball valve. Distal ends of the pin are connected to a collar (46) that is fitted about the spherical section (42). The collar has cam stops that abut an edge (102) of the upturned flange (104) of the seating ring (48). The spherical section (42) has inlet openings (90,94) that are configured with convex and concave sections to produce a desired flow pattern.
摘要:
A drain discharge device for discharging effluent comprises a valve with a single outlet and a plurality of inlets that selectively connects the single outlet to one of inlets in turn. The inlets, each of which corresponds to an outlet of an effluent discharging device, such as an air compressor or an after cooler, are each sequentially connected to the single outlet in order to drain effluent. Due to the sequential connection of the drain points to the outlet, the drain discharge device operates irrespective of air pressure differences at the drain points. In addition, since each drain point is connected to the outlet in sequence, the system avoids clogging by particulate foreign substances or lubricants. One embodiment discloses a device having a single valve serving three or more inlets. Embodiments employing a rotary ball valve and a linearly moving valve are both disclosed. In one ball valve embodiment, inlets and outlet are in the same plane. In a further ball valve embodiment, the inlets are all in one plane, and an axis of the outlet is orthogonal to this plane, and rotation of the ball valve is about the axis of the outlet.

A faucet valve 10 includes a ball valve 28 seated in a valve chamber 18. The ball valve 28 has a plurality of apertures 46 circumferentially spaced about the control stem 32 which extends through an opening 60 in the cap assembly 48 of the valve housing 16. A check valve 66 is formed within the hollow interior 62 of the ball valve and includes a disc section 70 that mounts a flap valve 78. A shield formed by a cylindrical wall 80 downwardly depending from the disc section 70 and a snap ring 84 fitted on the lower end of the cylindrical wall protects the flap valve from undue water turbulence. Negative pressure in the supply inlet opens the flap valve 78 to draw air through passageway 64 formed by the apertures 46 and auxiliary opening 60 and hollow interior 62 of the ball valve seated in the valve chamber 18.
摘要:
There is disclosed a mixing valve primarily for hot and cold water which includes a complex unitary removable seat unit formed by molding, to cooperate with a control member and seal of special form to control fluid flow into a valve body and through the same to a by-pass valve in the body which includes a spool arranged to operate in a horizontal position to cause fluid directed thereto, to be delivered to and from one outlet or another in response to opening and closing of one outlet.
摘要:
The single handle faucet disclosed herein comprises a faucet body which has a pair of inlets for hot and cold water and a liquid outlet. A spherical valve body is mounted for swinging movement within the body and has a spherical surface that is complementary to a similar compressible spherical surface on the faucet body. The valve body has passages extending from the spherical surface of the valve body. The passages of the valve body and the passages of the faucet body are adapted to be selectively aligned. The compressible spherical surface forms a part of a sealing member which defines a hydraulic seal on the faucet body.
摘要:
A single handle mixer valve comprising an elastomeric body which sealingly supports a spherical valve member for rotation about two mutually perpendicular axes to regulate degree and balance of flow between two fluid inlets and an outlet. Three embodiments are disclosed.
摘要:
A fluid-control valve having a spherical control member surrounded by a body having a chamber that conforms intimately with the surface of the control member. Fluid passageways are provided on the control member which are alignable with ports in the body when the member is nutated relative to the chamber. Fluid under pressure is thus selectively directed to hydraulic equipment to actuate a ram or other device.
