Abstract
A fluid supply control device and a gas combustion type nailer including the fluid supply control device are provided. The fluid supply control device includes a gauging chamber configured to be charged with a fluid, an inlet port through which the fluid flows into the gauging chamber, an outlet port through which the fluid flows out from the gauging chamber, a first valve element arranged inside the gauging chamber to close the inlet port, a second valve element arranged inside the gauging chamber to close the outlet port, an electromagnetic biasing structure configured to electromagnetically bias the first valve element and the second valve element, and an elastic biasing structure configured to elastically bias at least one of the first valve element and the second valve element. The first valve element and the second valve element are independently movable and are actuated with a time difference.
