Abstract
Abstract A straightway valve comprising a body with a through hole accommodating a coaxially mounted sleeve. The sleeve is secured to the body at the side where a working fluid is admitted into the sleeve. The sleeve is arranged so that there is a passage between its external surface and the internal surface of the body. The side surface of the sleeve is provided with ports for communicating the sleeve with the passage for the working fluid. Each port is closed by a flexible plate cantilevered to the external surface of the sleeve. The flexible plate has a variable width decreasing towards the point of its fastening to the sleeve so that the ratio of the port-closing portion of the plate to the width of its remaining flexible portion is 8:1.1.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
179 words
A straightway valve including an inlet and an outlet for a working fluid, and comprising: a body with an internal polyhedral surface; at least one through hole in said body; a sleeve installed coaxially in said hole and secured to said body at the side of said inlet, said sleeve having an external polyhedral surface, defining an inner space, and being installed so as to form a passage between said external surface of the sleeve and said internal surface of the body; ports on the side surface of said sleeve for communicating said inner space with said passage; additional channels for said outlet of the working medium at places of intersection of edges made in said body hole at the level of said ports; flexible plates cantilevered between said body and said sleeve; said plates having port-closing and resilient portions; said plates closing said ports and having a variable width decreasing towards the points of plate fastening to said sleeve so that the ratio of the widths of said port-closing portions to that of said resilient portions is 8:1.1.
Claim 2
Dependent Claim
179 words
A straightway valve including an inlet and an outlet for a working fluid, and comprising: a body with an internal polyhedral surface; at least one through hole in said body; a sleeve installed coaxially in said hole and secured to said body at the side of said inlet, said sleeve having an external polyhedral surface, defining an inner space, and being installed so as to form a passage between said external surface of the sleeve and said internal surface of the body; ports on the side surface of said sleeve for communicating said inner space with said passage; additional channels for said outlet of the working medium at places of intersection of edges made in said body hole at the level of said ports; flexible plates cantilevered between said body and said sleeve; said plates having port-closing and resilient portions; said plates closing said ports and having a variable width decreasing towards the points of plate fastening to said sleeve so that the ratio of the widths of said port-closing portions to that of said resilient portions is 8:1.1.
Claim 3
Dependent Claim
46 words
The straightway valve as defined in claim 1, wherein said plates have a variable thickness decreasing towards said fastening points so that the ratio of the thickness of said port-closing portions for the passage of the working fluid to that of said resilient portions is 3:1.
Claim 4
Dependent Claim
20 words
The straightway valve as defined in claim 1, wherein said plates have at least one hole in said resilient portions.
