Abstract
Abstract A leaching chamber (10) includes first and second side walls (46) which have louver sections. The side walls are connected by vaulted portion (48) to define a chamber potion (12) terminating at a first end (16) and a second end (18). Male and female coupling collars (20, 30) are integrally connected with corrugation peaks at the first and second ends. An intermediate peak or structure (70) has a first portion (72) with a profile of the male coupling collar and a second portion (74) with a profile of the female coupling collar upon cutting between the two portions, two subchambers (12', 12") are formed each having a female coupling collar at one end and a male coupling collar at the other. An inlet end cap (14) is telescopically connected to the female coupling collar (30). The inlet end cap (14) has a sleeve (102) to receive a conduit carrying effluent and a diffuser (104) to diffuse the received effluent. The diffuser includes a sloping surface with diverging ribs (106). A sloping surface (108) extends along a bottom edge of the end cap aligned with the diffuser to absorb the erosion inducing force of fluid falling from the diffuser.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
100 words
A chamber for receiving fluids to be dispersed, the chamber comprising: separated side walls, each side wall having louvers defined therein to allow the fluid to be dispersed therethrough; vaulted portions spanning upper edges of the side walls, the vaulted portions and the side walls terminating at a first end including a first coupling construction and at a second end including a second coupling construction; and an inlet end cap connected with the first end coupling construction, the inlet end cap including: an inlet for receiving a fluid conveying conduit; a diffuser contiguous to the inlet for diffusing received fluid.
Claim 2
Dependent Claim
100 words
A chamber for receiving fluids to be dispersed, the chamber comprising: separated side walls, each side wall having louvers defined therein to allow the fluid to be dispersed therethrough; vaulted portions spanning upper edges of the side walls, the vaulted portions and the side walls terminating at a first end including a first coupling construction and at a second end including a second coupling construction; and an inlet end cap connected with the first end coupling construction, the inlet end cap including: an inlet for receiving a fluid conveying conduit; a diffuser contiguous to the inlet for diffusing received fluid.
Claim 3
Dependent Claim
36 words
The chamber as set forth in claim 1 wherein the inlet end cap further includes an angled surface extending along a bottom edge and substantially aligned with and below the diffuser to deflect the received fluid.
Claim 4
Dependent Claim
16 words
The chamber as set forth in claim 2 wherein the angled surface includes a second rib.
Claim 5
Dependent Claim
27 words
The chamber as set forth in claim 1 wherein the diffuser includes a sloping surface and of at least one first rib which diverges from the inlet.
Claim 6
Dependent Claim
129 words
The chamber as set forth in claim 1 wherein the first coupling construction includes a first male arch and the second coupling construction includes a first female arch, the female arch defining an inner cross section which is larger than an outer dimension of the male arch such that the male arch is telescopically receivable within the female arch and further including: an integrally connected second male arch and second female arch, the second male arch having the same outer dimension as the first male arch and the second female arch having the same inner cross section as the first female arch, the integrally connected second male and female coupling arches being integrally connected with the side walls and the vaulted portions midway between the first and second ends.
Claim 7
Dependent Claim
106 words
A dispersion chamber for subterranean dispersion of fluids, the chamber comprising: separated side walls, each side wall having dispersion apertures defined therein to allow the fluid to pass therethrough; a vaulted portion extending between the side walls to define a chamber terminating at first and second ends; a first coupling collar integrally connected to the side walls and the vaulted portion at the first end; an inlet end cap selectively connected with the first end collar, the end cap having an inlet for receiving the fluid to be dispersed and a diffuser below the inlet to diffuse the received fluid into an interior of the chamber.
Claim 8
Dependent Claim
106 words
A dispersion chamber for subterranean dispersion of fluids, the chamber comprising: separated side walls, each side wall having dispersion apertures defined therein to allow the fluid to pass therethrough; a vaulted portion extending between the side walls to define a chamber terminating at first and second ends; a first coupling collar integrally connected to the side walls and the vaulted portion at the first end; an inlet end cap selectively connected with the first end collar, the end cap having an inlet for receiving the fluid to be dispersed and a diffuser below the inlet to diffuse the received fluid into an interior of the chamber.
Claim 9
Dependent Claim
38 words
The chamber as set forth in claim 6 wherein the side walls include sections of integral louvers generally between which the apertures are defined, adjacent louver sections being offset from one another and connected by generally parallel webs.
Claim 10
Dependent Claim
40 words
The chamber as set forth in claim 6 wherein the inlet end cap further includes an inwardly projecting surface extending along a bottom edge and substantially vertically aligned with the diffuser to deflect the fluid after falling from the diffuser.
Claim 11
Dependent Claim
43 words
The chamber as set forth in claim 6 wherein a cylindrical sleeve surrounds the inlet and the diffuser includes a sloping surface extending inward from the inlet and a plurality of ribs projecting upward from the sloping surface and diverging from the inlet.
Claim 12
Dependent Claim
55 words
The chamber as set forth in claim 9 further including a second coupling collar integrally connected to the side walls and the vaulted portion at the second end, the first and second coupling collars having first and second profiles that are telescopically receivable, such that a plurality of the chambers are couplable end to end.
Claim 13
Dependent Claim
96 words
The chamber as set forth in claim 10 wherein the side walls and the vaulted portion include an integral intermediate section having a first portion with the profile of the first coupling collar and a second portion with the profile of the second collar, the first and second portions being integrally formed with a cutable plastic material such that upon cutting between the first and second portions two subchambers are formed, each subchamber having a coupling collar with the first profile at one end and a coupling collar with the second profile at the other end.
Claim 14
Dependent Claim
116 words
