Abstract
A multiple valve control assembly is described. The multiple valve control assembly includes a first cam/lever assembly to close a first valve, and a second cam/lever assembly to close a second valve. A first locking surface of the first cam/lever assembly, when the first cam/lever assembly is in the open position, physically blocks the rotation of the second cam/lever assembly. This provides for a pressure line to be closed by the first cam/lever assembly before the tank line can be closed by the second cam/lever assembly.
Claims19
A multiple valve control assembly, comprising:
- a support member;
- a first valve, comprising:
- a first entry port;
- a first exit port;
- a second valve, comprising:
- a second entry port;
- a second exit port;
- a first cam engaged to the first valve to open and close the first valve, the first cam comprising a first peripheral surface having a first locking surface and a first concave surface;
- a second cam engaged to the second valve to open and close the second valve, the second cam comprising a second peripheral surface having a second locking surface and a second concave surface;
- the first cam configured to rotate between an open position and a closed position, the second cam configured to rotate between an open position and a closed position, wherein the first locking surface of the first cam, in the open position, prevents the rotation of the second cam;
- and,
- wherein a lock is rotatably engaged to the support member, and the lock rotates between locked and unlocked positions.

A multiple valve control assembly, comprising:
- a support member;
- a first valve, comprising:
- a first entry port;
- a first exit port;
- a second valve, comprising:
- a second entry port;
- a second exit port;
- a first cam engaged to the first valve to open and close the first valve, the first cam comprising a first peripheral surface having a first locking surface and a first concave surface;
- a second cam engaged to the second valve to open and close the second valve, the second cam comprising a second peripheral surface having a second locking surface and a second concave surface;
- the first cam configured to rotate between an open position and a closed position, the second cam configured to rotate between an open position and a closed position, wherein the first locking surface of the first cam, in the open position, prevents the rotation of the second cam, and

8 more elements
A multiple valve control assembly for a fluidic system, comprising:
- a support member;
- a first valve in a first fluid line;
- a second valve in a second fluid line;
- a first cam rotatably engaged to the support member, the first cam engaged to the first valve to open and close the first valve, the first cam comprising a first peripheral surface having a first locking surface and a first concave surface;
- a second cam rotatably engaged to the support member, the second cam engaged to the second valve to open and close the second valve, the second cam comprising a second peripheral surface having a second locking surface and a second concave surface;
- and,
- the first cam configured to rotate between an open position and a closed position, the second cam configured to rotate between an open position and a closed position, wherein the first locking surface of the first cam, in the open position, prevents the rotation of the second cam, and, when the first cam is in the closed position, the first concave surface receives the second locking surface of the second cam;
- and
- wherein the first cam and the second cam include one or more tool receiving points, one or more tool openings, knurls, indentations, knobs, handles, or other raised surface for an operator to grip to rotate the first and second cams.
6 more elements
A valve control assembly, comprising:
- a valve;
- a cam engaged to the valve to open and close the valve;
- the cam comprising a peripheral surface having a locking surface and a concave surface;
- a support member;
- and,
- a lock is rotatably engaged to the support member, and the lock rotates between locked and unlocked positions;
- and
- the lock includes a lock indent, and the support member includes a lock opening, and a secondary lock is configured to pass through the lock indent and the lock opening to prevent the rotation of the cam.
5 more elements
A valve control assembly, comprising:
- a valve;
- a cam engaged to the valve to open and close the valve;
- the cam comprising a peripheral surface having a locking surface and a concave surface;
- a support member;
- and,
- a lock is rotatably engaged to the support member, and the lock rotates between locked and unlocked positions, wherein the lock includes a convex surface that extends into the concave surface of the cam to prevent rotation of the cam when the lock is in the locked position;
- and,
- wherein the cam is color coded to match a type of fluid.
