Abstract
Abstract A device is disclosed for absorbing the energy of a fluid cutting jet after it has passed through the workpiece in order to reduce the sound level as well as the spray and vapor normally accompanying the fluid jet cutting process. The device includes a baffle arrangement disposed immediately adjacent the workpiece and enclosed in a housing to receive and contain the jet after it has passed through the workpiece so as to prevent the sonic energy and spray from emanating into the surrounding environment. The jet itself is directed through the baffle arrangement to impact a liquid bath, backed up with a hardened steel block, thereby dissipating its momentum.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
91 words
An energy absorber for receiving a high velocity jet of liquid comprising: a housing disposed to receive said high velocity jet and substantially enclose it; means within said housing to absorb said high velocity fluid jet energy, including baffle means surrounding said fluid jet after it enters said housing and preventing sound and spray from passing back out of said housing, comprising a volume of resilient material having a passage therethrough to receive said jet whereby sound and spray from said jet is substantially prevented from passing into the surrounding environment.
Claim 2
Dependent Claim
91 words
An energy absorber for receiving a high velocity jet of liquid comprising: a housing disposed to receive said high velocity jet and substantially enclose it; means within said housing to absorb said high velocity fluid jet energy, including baffle means surrounding said fluid jet after it enters said housing and preventing sound and spray from passing back out of said housing, comprising a volume of resilient material having a passage therethrough to receive said jet whereby sound and spray from said jet is substantially prevented from passing into the surrounding environment.
Claim 3
Dependent Claim
26 words
The absorber of claim 1 wherein said means to absorb said fluid jet energy includes a liquid bath disposed to be impacted by said fluid jet.
Claim 4
Dependent Claim

Claim 5
Dependent Claim
98 words
In a system for fluid jet cutting wherein a high velocity jet is directed at a workpiece to sever the same, the improvement comprising: energy absorbing means including a housing disposed to receive and substantially contain said fluid jet immediately after passing through said workpiece and also including means in said housing to absorb the energy of said fluid jet including baffle means surrounding said fluid jet after it enters said housing and preventing sound and spray from passing back out of said housing, comprising a volume of resilient material having a passage therethrough to receive said jet.
Claim 6
Dependent Claim
98 words
In a system for fluid jet cutting wherein a high velocity jet is directed at a workpiece to sever the same, the improvement comprising: energy absorbing means including a housing disposed to receive and substantially contain said fluid jet immediately after passing through said workpiece and also including means in said housing to absorb the energy of said fluid jet including baffle means surrounding said fluid jet after it enters said housing and preventing sound and spray from passing back out of said housing, comprising a volume of resilient material having a passage therethrough to receive said jet.
