Abstract
Abstract A power plant for connection to a main pipe conveying a pressure medium such as natural gas, includes a branch pipe connected to the main pipe, an energy conversion device such as a turbine or a piston pump connected to receive pressure medium from the branch pipe and operable to convert pressure energy of the medium into usable energy, and an intermediate buffer reservoir connected to receive pressure medium from the conversion device and supplying the pressure medium from the reservoir to a load which consumes pressure medium.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
77 words
A power plant comprising: (i) a pressure medium conveying main pipe (ii) a branch pipe connected to said main pipe (iii) an energy conversion device connected to receive pressure medium from said branch pipe and operable to convert pressure energy of said medium into usable energy, and (iv) an intermediate buffer reservoir connected to receive pressure medium from said conversion device and adapted to supply said pressure medium from said reservoir to a pressure medium consuming load.
Claim 2
Dependent Claim
77 words
A power plant comprising: (i) a pressure medium conveying main pipe (ii) a branch pipe connected to said main pipe (iii) an energy conversion device connected to receive pressure medium from said branch pipe and operable to convert pressure energy of said medium into usable energy, and (iv) an intermediate buffer reservoir connected to receive pressure medium from said conversion device and adapted to supply said pressure medium from said reservoir to a pressure medium consuming load.
Claim 3
Dependent Claim
22 words
A power plant, as claimed in claim 1, wherein said reservoir is connected to supply a plurality of pressure medium consuming loads.
Claim 4
Dependent Claim
21 words
A power plant, as claimed in claim 1, comprising a further energy conversion device provided between said reservoir and said load.
Claim 5
Dependent Claim
24 words
