摘要： It is an object to provide a servo valve that can be manufactured at low cost by simplifying adjustment of the relative position between a nozzle and a flapper and simplifying the configuration of a valve-element driving circuit. Provided is a servo valve (1) including a spool (5) mounted so as to be movable back and forth; a first chamber (7) and a second chamber (9) that mutually push the spool (5) in opposite directions by means of fluid pressure; and a spool driving circuit (3) that supplies oil to the first chamber (7) and the second chamber (9) and that adjusts the pressure of supplied oil to move the spool (5) back and forth, wherein the spool driving circuit (3) maintains the fluid pressure of the first chamber (7) at a substantially constant level and includes, at an oil outlet of the second chamber (9), a nozzle flapper mechanism (27) that adjusts the fluid pressure of the second chamber (9).

摘要： A poppet valve includes: a valve seat (56); a poppet (58) disposed so as to face the valve seat; an actuator (60) for driving the poppet; a first valve casing (62) which houses the actuator and which includes a contact surface (62a) capable of making contact with an end surface of the poppet opposite to the valve seat; and a thermally sprayed layer (64) including a non-magnetic material, formed on at least a part of the end surface of the poppet or the contact surface of the first valve casing. A Vickers hardness Hv1 of the end surface of the poppet or the contact surface of the first valve casing and a Vickers hardness Hv2 of the thermally sprayed layer satisfy a relationship (Hv1-50Hv)≤Hv2≤(Hv1+100Hv).

摘要： An annular valve (50, 70) includes an annular valve seat (51) including a seat portion (52) formed by an outer circumferential edge (34a) and an inner circumferential edge (34b) of an annular opening (34), a rod (53) configured to be movable along a direction orthogonal to the seat portion (52), an annular valve body (54) disposed so as to face the annular valve seat (51) and fixed to the rod (53), and a valve-body moving unit (55) for moving the annular valve body (54) between: a valve-closed position in which the annular valve body (54) contacts the seat portion (52) of the annular valve seat (51) so that the annular opening (34) is closed by the annular valve body (54); and a valve-open position in which the annular valve body (54) is positioned away from the seat portion (52) of the annular valve seat (51) so that the annular opening (34) is open. The seat portion (52) of the annular valve seat (51) is configured to be in surface contact with the annular valve body (54) in the valve-closed position in a first annular region (52a) including the outer circumferential edge (34a) of the annular opening (34) and in a second annular region (52b) including the inner circumferential edge (34a) of the annular opening (34).
