Claims

[Claims for Utility Model Registration] 1. A valve body, a first cavity formed in the valve body, a second cavity formed in the valve body, and a first cavity formed in the valve body. a first input port connecting the first cavity and the air tank; a second input port formed in the valve body and connecting the second cavity and the air tank; and a second input port formed in the valve body. an output port that connects the first cavity and the operating cylinder; a communication hole that is formed in the valve body and connects the first cavity and the second cavity; and a communication hole that is formed in the valve body and connects the first cavity and the second cavity. an exhaust port that opens the second cavity to the atmosphere; a position that is slidably provided in the first cavity and communicates the first input port and the output port; and a position that communicates the output port with the output port. a first valve that is selectively located at a position that communicates with the hole; a first valve that is slidably provided in the second cavity and that communicates with the second input port and the communication hole; A solenoid valve comprising: a second valve selectively located at a position communicating with the exhaust port; a first solenoid that moves the first valve; and a second solenoid that moves the second valve. 2 one valve body; a first cavity formed in the valve body; a second cavity formed in the valve body; a first input port for connecting the tank; a second input port formed in the valve body for connecting the second cavity and the air tank; and a second input port for connecting the air tank and the second cavity, and a second input port formed in the valve body and connected to the actuating cylinder. a double output port connected to the first cavity and the second cavity, selectively communicating the output port with the first cavity or the second cavity;
a check valve; a first exhaust port formed in the valve body to vent the first cavity to the atmosphere; and a second exhaust port formed in the valve body to vent the second cavity to the atmosphere. a port slidably provided in the first cavity, a position communicating the first input port and the double check valve, and a position communicating the double check valve and the first exhaust port; a first valve that is slidably provided in the second cavity and that communicates the second input port with the double check valve; A solenoid valve comprising: a second valve selectively located at a position communicating with a second exhaust port; a first solenoid that moves the first valve; and a second solenoid that moves the second valve.
