Abstract
A faucet having a body extending from forward to aft ends to define a body cavity, the body includes an aft wall having faucet inlet ports, and a faucet outlet between the forward and aft ends; a push knob coupled to the body forward end; a cartridge fixed within the body cavity, the cartridge has a cartridge cavity with an aft seal seat, a cartridge outlet port forward of the aft seal seat, and a cartridge inlet port aft of the aft seal seat; a piston within the cartridge cavity, defining an aft seal lip: the piston is movable by the push knob from first to second positions, to move the lip and open the faucet; and the piston moves from the second to the first positions, to position the lip against the aft seal seat and close the faucet; and a linear damper, mounted to the body forward end.
Claims19
A faucet comprising:
- a body, extending from a forward end to an aft end to define a body cavity, wherein the body includes an aft wall that defines faucet inlet ports, and the body defines a faucet outlet between the forward and aft ends;
- a push knob, operationally coupled to the forward end of the body;
- a cartridge, fixed within the body cavity, wherein the cartridge defines a cartridge cavity that has an aft seal seat, a cartridge outlet port that is forward of the aft seal seat, and a cartridge inlet port that is aft of the aft seal seat;
- a piston that is seated within the cartridge cavity, the piston defining an aft seal lip, wherein:
- the piston is movable by the push knob from a first position to a second position, to move the lip away from the seal seat and open the faucet;
- and
- the piston is movable by a spring from the second position to the first position, to position the lip against the aft seal seat and close the faucet;
- and
- a linear damper, mounted to the forward end of the body, wherein the linear damper engages the piston to dampen movement of the piston from the second position to the first position;
- the forward end of the piston defines a forward piston cavity that extends aft to a location that is intermediate the forward and aft ends of the piston;
- and
- the linear damper extends from a forward end that extends forward of the forward end of the body to an aft end that extends into the forward piston cavity, and the damper includes a plunger extending aft from the aft end of the damper to engage the piston.
A faucet comprising:
- a body, extending from a forward end to an aft end to define a body cavity, wherein the body includes an aft wall that defines faucet inlet ports, and the body defines a faucet outlet between the forward and aft ends;
- a push knob, operationally coupled to the forward end of the body;
- a cartridge, fixed within the body cavity, wherein the cartridge defines a cartridge cavity that has an aft seal seat, a cartridge outlet port that is forward of the aft seal seat, and a cartridge inlet port that is aft of the aft seal seat;
- a piston that is seated within the cartridge cavity, the piston defining an aft seal lip, wherein:
- the piston is movable by the push knob from a first position to a second position, to move the lip away from the seal seat and open the faucet;
- and
- the piston is movable by a spring from the second position to the first position, to position the lip against the aft seal seat and close the faucet;
- and
- a linear damper, mounted to the forward end of the body, wherein the linear damper engages the piston to dampen movement of the piston from the second position to the first position,
- wherein:
- the aft end of the body includes:
- a backplate;
- and
- forward and aft gaskets that are forward and aft of the backplate,
- wherein:
- the backplate defines first and second apertures for receiving terminal ends of feed lines that are connected to the faucet inlet ports;
- and
- the backplate is mountable between the aft wall of the body and an exterior structure.
