Abstract

PURPOSE: To simplify piping and reduce cost by integrally forming three functions, namely switching to oil cooler due to temperature rise, filtration of oil, and openingclosing of circuit due to pressiure increase, in to a valve.
CONSTITUTION: When a valve is used in a circuit of an air compressor 27, for example, pressure operates to a port 22 through the driving of the compressor 27, and a stop vlave 25 is set at open position. If the oil which flows from a receptacle 28 is in warm state at this time, oil is supplied into a chamber 11 from a port 14, and a thermovalve 24 closes a port 15, and the oil is supplied to an oil cooler 29 through chambers 11 and 9 and a port 8, and introduced into a port 3, a chamber 12, and a filter (not shown in the figure), and recirculates into the compressor 27 and a tank 28 through a chamber 13, a port 19, a chamber 21, and a port 20. When the oil is in cold state, the valve 24 is opened, and the oil passes through a port 15, and passes through chambers 11 and 13, port 19, chamber 21, and the port 20, and goes into the compressor 27.
