Abstract
A manifold valve has a larger valve port, through which a spool slides, than conventional relative to the size of the valve body. When the size of the valve port is fixed, the size of the entire valve can be made smaller. The walls on both sides of the valve port have no holes to pass bolts to fasten the valve body to a manifold base etc. The side walls are at least made thinner than the walls having bolt holes, within the limit in which the strength to withstand the pressure of the fluid passing therethrough remains unimpaired. The valve is fastened to the valve mounting surface of the manifold base etc. by clamping at its front and rear ends.
Claims20
A manifold valve used on a valve mounting surface of one of a sub-soleplate and a manifold base having openings corresponding to ports therein in which:
- (a) a valve port is provided in a valve body of the manifold valve to slidably accommodate a spool that switches passages of a pressurized fluid flowing therethrough;
- (b) walls on both sides of the valve port have no holes to pass bolts to fasten the valve body to the one of a sub-soleplate and a manifold base;
- and
- (c) means for connecting the valve body to the one of a sub-soleplate and a manifold base are provided without utilizing bolts on said both sides of the valve port such that said side walls can be made thinner as compared with walls having bolts holes, while the limit in which the strength to withstand the pressure of the fluid passing therethrough remains unimpaired, wherein the valve body is fastened to the valve mounting surface of the one of a sub-soleplate and a manifold base by clamping at the front and rear ends thereof;
- and
- wherein the one of a sub-soleplate and a manifold base has a metal clamp at a front end of the valve mounting surface thereof, a metal lock switchable between the locking and releasing positions at a rear end thereof, and means to switch the position of the metal lock by operation from the front end of the valve mounting surface, and the valve mounted on the valve mounting surface has a pair of engaging recesses to engage with the metal clamp and the metal lock in the locking position.
A manifold valve used on a valve mounting surface of one of a sub-soleplate and a manifold base having openings corresponding to ports therein in which:
- (a) a valve port is provided in a valve body of the manifold valve to slidably accommodate a spool that switches passages of a pressurized fluid flowing therethrough;
- (b) walls on both sides of the valve port have no holes to pass bolts to fasten the valve body to the one of a sub-soleplate and a manifold base;
- and
- (c) means for connecting the valve body to the one of a sub-soleplate and a manifold base are provided without utilizing bolts on said both sides of the valve port such that said side walls can be made thinner as compared with walls having bolts holes, while the limit in which the strength to withstand the pressure of the fluid passing therethrough remains unimpaired;
- wherein said means for connecting includes a movable lock and a clamp, and means for moving said movable lock between lock and release positions, said means for moving including a control bolt associated with said clamp;
- the valve further including a cam and a lock lever connected between said control bolt and said movable lock, and wherein rotation of said control bolt causes movement of said lock by way of said cam and lock lever.
A manifold valve comprising:
- (a) a valve body having a first valve body engaging mechanism and a second valve body engaging mechanism;
- (b) a manifold base;
- (c) a first lock mechanism engageable with said first valve body engaging mechanism;
- (d) a second lock mechanism engageable with said second valve body engaging mechanism;
- and
- (e) a connecting member connecting said first lock mechanism and said second lock mechanism;
- wherein said connecting member is a linkage mechanically coupling said first lock mechanism and said second lock mechanism such that said second lock mechanism is locked to said second valve body engaging mechanism via said connecting member upon operation of said first lock mechanism engaging said first valve body engaging mechanism.
A system of manifold valves comprising:
- a plurality of manifold valves, each of said manifold valves comprising:
- (a) a valve body having a first valve body engaging mechanism and a second valve body engaging mechanism;
- (b) a manifold base;
- (c) a first lock mechanism engageable with said first valve body engaging mechanism;
- (d) a second lock mechanism engageable with said second valve body engaging mechanism;
- and
- (e) a connecting member connecting said first lock mechanism and said second lock mechanism;
- wherein said connecting member is a linkage mechanically coupling said first lock mechanism and said second lock mechanism such that said second lock mechanism is locked to said second valve body engaging mechanism via said connecting member upon operation of said first lock mechanism engaging said first valve body engaging mechanism.
