Abstract
Abstract A reservoir assembly for use as a fluid storage component in systems for actuating hydraulically operated devices. An apertured diffuser is disposed within the reservoir for reducing the velocity of fluid returning to the reservoir without decreasing the rate of fluid flow. In one aspect of the invention, the reservoir assembly is made entirely of a noncorrosive material to prevent contamination of the hydraulic fluid. To this end, for example, the reservoir comprises a one piece, seamless plastic container, while the diffuser is likewise, for example, made of plastic material.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
150 words
A reservoir assembly for a hydraulic system having a highpressure return flow from a hydraulically activated device in the hydraulic system, said reservoir assembly comprising: a seamless reservoir for storing hydraulic fluid, said seamless reservoir being formed from a non-corrosive material to prevent said seamless reservoir from producing contaminant particles to contaminate the hydraulic fluid stored in said seamless reservoir and having port means for passing hydraulic fluid to and from said seamless reservoir; cylindrical diffuser means positioned over said port means in said reservoir, said diffuser means having a plurality of apertures therein, the number of said apertures being sufficient to reduce the velocity of hydraulic fluid flow into said seamless reservoir without decreasing the rate of flow of hydraulic fluid into said seamless reservoir; and means for coupling said reservoir to said hydraulically activated device to permit flow of hydraulic fluid to and from said hydraulically activated device.
Claim 2
Dependent Claim
150 words
A reservoir assembly for a hydraulic system having a highpressure return flow from a hydraulically activated device in the hydraulic system, said reservoir assembly comprising: a seamless reservoir for storing hydraulic fluid, said seamless reservoir being formed from a non-corrosive material to prevent said seamless reservoir from producing contaminant particles to contaminate the hydraulic fluid stored in said seamless reservoir and having port means for passing hydraulic fluid to and from said seamless reservoir; cylindrical diffuser means positioned over said port means in said reservoir, said diffuser means having a plurality of apertures therein, the number of said apertures being sufficient to reduce the velocity of hydraulic fluid flow into said seamless reservoir without decreasing the rate of flow of hydraulic fluid into said seamless reservoir; and means for coupling said reservoir to said hydraulically activated device to permit flow of hydraulic fluid to and from said hydraulically activated device.
Claim 3
Dependent Claim
35 words
The reservoir assembly of claim 1 wherein said diffuser means is formed from a non-corrosive material to prevent said diffuser means from producing contaminant particles to contaminate the hydraulic fluid stored in said seamless reservoir.
Claim 4
Dependent Claim
17 words
The reservoir assembly of claim 2 wherein said seamless reservoir is rotationally molded from high density polyethylene.
Claim 5
Dependent Claim
15 words
The reservoir of claim 3 wherein said diffuser means is formed from high density polyethylene.
