Abstract: A flow-control faucet aerator is configured to be fitted on a spout of a faucet and includes a housing, an aerating device installed in the housing, and a washer installed above the aerating device. The washer is provided with at least one mouth and an aqueduct circling the mouth. The aqueduct is made of an elastic material and has a neck that has a wall thickness smaller than a wall thickness of the rest of the aqueduct. The neck of the aqueduct deforms at different levels according to different levels of water pressure at the spout of the faucet, so as to change a diameter of the aqueduct and in a flow of the faucet, thereby contributing to flow control and water conservation.

Abstract: A hydraulic pressure damping device mainly comprises a valve body of which a joint port is provided with a control valve of which one end is provided with a first joint to valve a switch of the valve body between a water inlet and a water outlet. A second joint at the other end of control valve is conjoint with a hydraulic pressure damper to damp the hydraulic pressure. Thus, it is easy to assemble and replace the hydraulic pressure damping device, and materials and installation space may be saved.

Abstract: A quick release device for faucets mainly includes a valve and a quick release unit. The valve is connected to at least two passages through which water flows, at least one passage is formed with a concave joint slot the inner circumference of which is formed with a shift limit slot. The quick release joint unit is oppositely arranged in the joint slot, and a shift limit unit is provided in the quick release joint and may be thereby fixed in the shift limit slot. A pipeline is provided that may be quickly installed on and removed from the quick release joint group. Thus, the installation time may be saved, the complicated installation steps may be reduced, and the area where flowing water contacts the metal may be decreased.

Abstract: An anti-freezing hydrant is provided with a hollow valve rod of which a back end is provided with a lump formed with an oblique cone where a water leakage hole is formed communicating with the valve rod. A one-way valve is provided in a inner water inlet in a valve chamber of a valve and comprises a rubber cushion being made of a soft rubber and thus elastically suppressing the inner water inlet. The bore of a back pressure stopper in a back pressure is a complement of an inner inclined cone with the oblique cone. Thus, the rubber cushion may enhance the capability of sealing of the valve. Further, the back pressure stopper may also be a good sealant for the inclined cone.

Abstract: A wall type shower faucet including a mixing valve and a faucet body having: first and second water inlet channels communicating with the mixing valve; a first load control passage in communication with the first water inlet channel; a second load control passage in communication with the second water inlet channel; a first rear passage communicating with the first water inlet channel; a second rear passage communicating with the second water inlet channel; a first water supply channel communicating with the first rear passage; and a second water supply channel communicating with the second rear passage. A junction pin cap is mounted in each first and second rear passage with a movable stem member mounted in each junction pin cap. Each movable stem member has a sealing washer and a tip portion extending into the associated load control passage.

Abstract: An improved structure for a water faucet control cartridge including an eccentrically arranged valve at the lower extent of the flow guide disk. The eccentrically arranged valve is of plastic construction and has an internal offset flow passage that enables water to flow from the water output seat of the faucet to the flow guide disk. The valve has a flat, semicircular, top surface for sealing against the flow disk.
