Latest Patents

One of Matsuzaki's latest patents is a hydraulic control apparatus. This apparatus includes a switch valve, a valve support chamber, a flow control valve that is movable within the valve support chamber, an on-off valve that is movable within the communication path chamber, and a valve control device. The flow control valve features a communication path chamber and a back pressure chamber. The on-off valve is capable of opening and shutting off a communication path between a cylinder line and a switch valve line. A restrictor is formed between the flow control valve and a wall defining the valve support chamber, connecting the cylinder line and the communication path chamber. The opening degree of the restrictor changes in correspondence with the movement of the flow control valve. When the switch valve is located at the neutral position or the supply position, the valve control device applies fluid pressure in the cylinder line to the back pressure chamber, urging the on-off valve to shut off the communication path. Conversely, when the switch valve is at the drainage position, the valve control device applies a pilot pressure lower than the fluid pressure in the cylinder line to the back pressure chamber, moving the on-off valve to open the communication path.

Another notable patent involves a valve seat arranged between the supply circuit and a downstream circuit. The valve body blocks fluid flow between the supply circuit and the downstream circuit by contacting the valve seat. The valve body connects the supply circuit to the downstream circuit for supplying fluid by separating from the valve seat. A through hole extends through the valve body, defining part of the supply circuit. The design of the through hole allows fluid to flow from it to the downstream circuit while minimizing pressure loss.
