Claims

[Scope of utility model registration request]

a body having a first port and a second port; a spool having a central land and two outer side lands slidably inserted into a hole provided in the body; The main body includes a detection core connected to the spool for detection and a position detector for detecting the movement of the core in a non-contact manner, and the main body has a central chamber communicating with the first port, and a detection core connected to the spool to detect the movement of the spool. two side chambers that are closed at zero wrap in neutral state by a central land of the spool and communicate with the second port; and two side chambers each partitioned by two side lands of the spool. end chambers, each of the two end chambers having a spring for biasing a spool such that the center land closes the center chamber to the side chambers with zero wrap when in neutral; A flow rate sensor, characterized in that the flow rate sensor is connected to one of a port and a second port, respectively.
