PROVISIONAL SPECIFICATION.
Improvements in Gaseous Fluid Compressors.
I, ALEXANDER JOHN ADAMSON, of 10 Rice Hey Road, Egremont, in the
County of Chester, Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention has reference generally to machinery for compressing gaseous
fluids as vapours, or gases; but more particularly to compressors used in connection
with refrigerating machinery; the part of such machinery to which the invention
refers, being the means of admitting the vapour or gas to the cylinder of single
acting compressors, that is, compressors in which the fluid to be compressed is
admitted to and compressed in one end only of the cylinder.
According to this invention, a piston rod end of a single acting compressor is
provided with or made in the form of a valve, which acts as an admission valve
for the fluid to the cylinder in the outstroke of the piston; while the piston itself
is provided on its inner side with an aperture with a seat round it, on which the
piston rod valve face acts. The other side of the piston is provided with a cover
or plate against which the back of the piston rod valve comes in the outstroke of
the piston, and so moves the piston in this stroke, while a space is provided round
the rod in an interior hollow part or space in the piston; and the vapour or gas
thus passes between the valve seat and the valve face into the cylinder.
The valve on the end of the piston rod is kept in place by suitable guides or
provisions inside the piston; and these, in some cases, may serve to receive studs
or bolts, by which the piston cover or plate is secured to the body. At the
periphery of the piston there will be an annular space or groove within which
suitable piston rings will be fitted.
In action, in the outstroke of the piston rod and piston of the compressor, the
valve on the piston rod is moved, by the movement of such rod, off the seat round
the inlet aperture in the piston, and comes against the plate or part on the opposite
side of the piston, and so opens the aperture for the inlet of the fluid during this
stroke. Then, in the return action, the valve is moved by the piston rod onto its
seat, and keeps the aperture closed, and presses the piston inwards against the
pressure of fluid within the cylinder, the compressed fluid being discharged through
a separate suitable outlet valve.

Improvements in Gaseous Fluid Compressors.
I, ALEXANDER JOHN ADAMSON, Engineer, of 10 Rice Hey Road, Egremont,
in the County of Cheshire, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention has reference generally to machinery for compressing gaseous

page_text: fluids as vapours or as gases, but more particularly to compressors used in connection
with refrigerating machinery; the part of such machinery to which the invention
refers, being the means of admitting the vapour or gas to the cylinder of single
acting compressors, that is, compressors in which the fluid to be compressed is
admitted to and compressed in one end only of the cylinder.
According to this invention, a piston rod end (referring to Figs. 1. and 2.) (A) of
-a single acting compressor is provided with, or made in the form of a valve, which
acts as an admission valve for the fluid to the cylinder in the outstroke of the
piston; while the piston (B) itself is provided on its inner side with an aperture
with a seat (C) round it, on which the piston rod valve face acts. The other side
of the piston is provided with a cover.or plate (D) against which the back of the
piston rod valve comes in the outstroke of the piston, and so moves the piston in
this stroke, while a space (E) is provided round the rod, in an interior hollow part
or space in the piston; and the vapour or gas thus passes between the valve seat
and the valve face into the cylinder.
The valve on the end of the piston rod is kept in place by suitable guides (F).or
provisions inside the piston; and these, in some cases, may erve to receive studs
or bolts, by which the piston cover or plate is secured to the body. At the
periphery of the piston there will be an annular space or groove within which
suitable piston rings will be fitted.
In action, in the outstroke of the piston rod and piston of the compressor, the
valve on the piston rod is moved by the movement of such rod, off the seat round
the inlet aperture in the piston and comes against the plate or part on the opposite
side of the piston, and so opens the aperture for the inlet of the fluid during the
stroke. Then, in the return action, the valve is moved by the piston rod on to its
seat, and keeps the aperture closed and presses the piston inwards against the
pressure of fluid within the cylinder, the compressed fluid being discharged through
a separate suitable outlet valve.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The combination of piston and inlet valve for gaseous fluid compressors and the
like, such that an enlargement of the piston rod forms the inlet valve, and the
piston body the valve seat, substantially as described and shown.
Dated this Second day of March 1897.
