Abstract
A negative pressure-side flow path having a negative pressure-side filter and a positive pressure-side flow path having a positive pressure-side filter are connected in parallel between a first port and a second port, and a shuttle valve is installed between the negative pressure-side flow path and the positive pressure-side flow path, and the first port, thus when a negative pressure is supplied to the first port, the first port is caused to communicate with the second port through the negative pressure-side flow path, and when a positive pressure is supplied to the first port, the first port is caused to communicate with the second port through the positive pressure-side flow path.
