摘要： A thrust control valve equipped with: a valve element (15), in which a gas injection passage (L), through which an operating gas (G) is injected, is formed, with a valve-seating surface (P1) being formed in the gas injection passage (L); and a valve stem (16), which is provided in the interior of the gas injection passage (L) and has a seated surface (P5) that makes contact with the valve-seating surface (P1). A guide surface (P4) which makes contact with the inner circumferential surface of the gas injection passage of the valve element (15) is formed on the outer circumferential surface of the valve stem (16). The guide surface (P4) is formed downstream from the seated surface (P5) in the direction of flow of the operating gas (G). A V-groove (31) through which the operating gas (G) flows is formed at the tip of the valve stem (16), downstream from the seated surface (P5) in which the guide surface (P4) is formed.
