Technical Field
The present disclosure relates generally to the field of shower conduit systems. More particularly, the present disclosure relates to an integral valve damper assembly for noise reduction in shower plumbing systems.
Background
Changes in water pressure generated by opening or closing valves in a residential shower system can be communicated to various components of the system by water in the system. The tubing and associated tubing set can amplify these pressure variations, creating annoying background noise. In some high flow rate systems, such as washing machines and dishwashers, the pressure variations may be severe enough to damage or cause collapse of the pipes (commonly referred to as "water hammer").
In addition, this pressure variation can lead to damage if the pipe is allowed to vibrate relative to other materials in the wall (e.g., steel studs). There are various additional solutions to solve the problem of severe water hammer in high flow systems. However, these additional solutions are often too bulky and over-designed to be used in low flow systems, such as residential shower systems. Furthermore, the use of such solutions may be limited by the need to position them near an access panel or open position in order to gain access to them for servicing.
Disclosure of Invention
At least one embodiment of the present disclosure is directed to a shower system. The shower system includes a shower waterway and a fluid control valve. The shower waterway is configured to be connected to a shower device. The fluid control valve is connected to the shower waterway and includes a valve body and a piston. The valve body includes a chamber and a reservoir. The piston is slidably connected to the valve body and fluidly separates the chamber from the reservoir. The chamber includes a compressible gas. The piston is configured to slidably translate within the valve body to compress the compressible gas in response to a change in water pressure in the shower waterway.
Another embodiment relates to a shower system. The shower system includes a fluid control valve configured to be connected to a shower waterway. The fluid control valve includes a valve body and a piston. The valve body includes a chamber and a reservoir. The piston is slidably connected to the valve body and fluidly separates the chamber from the reservoir. The chamber includes a compressible gas. The piston is configured to slidably translate within the valve body to compress the compressible gas in response to a change in water pressure in the shower system.
Another embodiment relates to a fluid control valve for a shower system. The fluid control valve includes a valve body and a piston. The valve body includes a chamber and a reservoir. The piston is slidably connected to the valve body and fluidly separates the chamber from the reservoir. The chamber includes a compressible gas. The piston is configured to slidably translate within the valve body to compress the compressible gas in response to a change in water pressure in the shower system.
Another embodiment relates to a valve damper assembly that is part of a valve body of a fluid control valve for a shower system. The valve body includes an internal cavity separated by a damper (e.g., a slidable piston) into a reservoir at a lower end and a chamber containing a compressible gas at an upper end. The valve damper assembly is configured such that when the valve opens/closes and a pressure change is generated, at least a portion of the water flow can be diverted into the reservoir such that the damper effectively absorbs the pressure change caused by the valve actuation. In this way, the volume of the chamber may be reduced as the pressure acting on the piston exceeds the opposing pressure exerted on the piston from the compressible gas contained within the chamber. The valve body may also include an adjustable vent for adjusting the amount of compressible gas in the chamber to adjust the relative position of the piston.

Detailed Description
Before turning to the figures, which illustrate one or more exemplary embodiments in detail, it is to be understood that the disclosure is not limited to the details or methodology set forth in the description or illustrated in the figures. It is also to be understood that the terminology used herein is for the purpose of description and should not be regarded as limiting.
Generally speaking, "water hammer brakes" are commonly used in high flow rate plumbing systems, such as washing machines and dishwashers (e.g., flow rates greater than 10gpm, etc.), to help reduce water hammer (i.e., sudden closing of a water valve can cause noise and vibration, resulting in pressure changes being transmitted through the plumbing system). In such a pipe system, when the valve is opened/closed, the instantaneous velocity of the water within the system may cause pressure spikes that may generate shock waves through the system, causing thump sounds or pipe vibrations. To absorb such shock waves, a water hammer brake may be installed upstream of the valve (i.e. before the valve in the system) so that when the valve suddenly closes, the pressure spike may be transferred to the brake to absorb the pressure change, rather than being transmitted through the piping system. However, the size of the water hammer brakes is typically large enough to absorb the pressure variations typically associated with these high flow rate systems. Furthermore, the bulky size of these devices may result in very limited applications where the water hammer brake may be installed within the system. In addition, these water hammer brakes are typically designed to handle significant forces that may be caused by pressure spikes that are typically only associated with high flow rate systems. Accordingly, there is a need for a smaller scale device that reduces or eliminates the noise associated with pressure variations experienced in low flow rate systems, such as residential shower systems.
Referring to the drawings in general, an integrated valve damper assembly for a residential shower system is disclosed herein. The disclosed valve damper assembly is designed to be integrated into the valve body of a fluid control valve that controls water flow through a shower system, thereby providing a more compact design and allowing easy access/maintenance compared to conventional water hammer brakes. The valve damper assembly has a structural configuration that is advantageously designed to account for pressure variations typically experienced in low flow rate systems (e.g., shower systems, which operate at flow rates of about 2-5 gpm). In addition, depending on the degree of pressure change experienced by a particular system, the valve damper assembly may advantageously be selectively adjusted to adapt the assembly to a particular application.

In operation, the pipe system 1 may experience a sudden flow disruption (e.g., a rapid opening or closing at the water outlet 120), which may generate a water pressure change (shown generally as a sinusoidal line segment flowing along path 2). Pressure changes will be transmitted through the valves and associated piping and may create noise and potential system damage. A valve damper (e.g.,
