Abstract
Abstract Installed co-axially in the valve body, along its axis, are two identical sockets with central holes in their bottoms, the holes forming seats closed by closing elements. The sockets are provided with annular seals which divide the valve body into three chambers, viz., an inlet chamber which receives the fluid under pressure, an outlet chamber communicating with the output element and a return chamber for draining the fluid from the output element back into the system. The sockets can be installed with their bottoms directed either towards each other to form a "normally-open" valve or away from each other to form a "normally-closed" valve. The closing elements are accommodated in cages and operated by a drive such as an electromagnetic drive. The critical limits of valve operation are set by springs.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
149 words
A ball-type valve intended for installation in hydraulic systems and comprising: a body with an essentially cylindrical inner space; two identical sockets installed coaxially in the body and provided with central holes in their bottoms the circular edges of the holes forming valve seats; ball closing elements co-operating with the seats with a possibility of valving them; annular seals mounted on the sockets and dividing the valve body into three chambers consisting of an inlet chamber for receiving a fluid under pressure, an outlet chamber communicating with the output element, and a return chamber for draining the fluid from the output element; a drive with a rod adapted to actuate the closing elements to open or close the valve; a pushrod installed along the axis of the valve body and intended to transmit motion from the rod to the closing elements; guides for the pushrod, made in the sockets.
Claim 2
Dependent Claim
149 words
A ball-type valve intended for installation in hydraulic systems and comprising: a body with an essentially cylindrical inner space; two identical sockets installed coaxially in the body and provided with central holes in their bottoms the circular edges of the holes forming valve seats; ball closing elements co-operating with the seats with a possibility of valving them; annular seals mounted on the sockets and dividing the valve body into three chambers consisting of an inlet chamber for receiving a fluid under pressure, an outlet chamber communicating with the output element, and a return chamber for draining the fluid from the output element; a drive with a rod adapted to actuate the closing elements to open or close the valve; a pushrod installed along the axis of the valve body and intended to transmit motion from the rod to the closing elements; guides for the pushrod, made in the sockets.
Claim 3
Dependent Claim
92 words
The valve acccording to claim 1 wherein at the "normally-closed" duty the bottoms of the sockets are directed away from each other and the seats of the bottoms co-operate with the closing elements installed outside in aligning separator cages, the closing element nearest to the valve inlet being acted upon by the fluid under pressure directed onto the seat while the other closing element bears against the drive rod and interacts with a pushrod which transmits the axial motion of the drive rod to the closing element nearest to the valve inlet.
Claim 4
Dependent Claim
40 words
The valve according to claim 1 wherein the bottoms of its sockets in the "normally-open" position face each other and there is a closing ball installed between the seats in the separator cage in operational contact with the drive rod.
Claim 5
Dependent Claim
33 words
The valve according to claim 1 wherein the drive rod mounts a spring which presses the rod towards the closing ball in the direction of the seat thus guaranteeing reliable rod-to-closing ball contact.
Claim 6
Dependent Claim
33 words
The valve according to claim 2 wherein the closing ball nearest to the valve inlet is in contact with a spring element which presses the closing ball against the seat and the pushrod.
Claim 7
Dependent Claim
41 words
The valve according to claim 4 wherein the socket accommodates a flexible element installed at the side of the fluid delivery channel and pressing the closing ball in the direction of the valve opening for communicating the inlet and outlet chambers.
Claim 8
Dependent Claim
43 words
The valve according to claim 2 wherein the separator cage is installed in a clamp between the socket and the adjacent thrust element with a provision for prompt replacement, each separator cage permitting only limited axial displacements of the closing ball it accommodates.
