Claims

[Scope of utility model registration request]

A rotary valve body 120 that is driven by a forward/reverse motor 130 to change its rotational angular position, a rotary valve body 110 on which the rotary valve body 120 is rotatably and slidably provided, and a rotary valve that detects the rotational angular position of the rotary valve body 120. The angle detector 140 is connected to the main suction pipe 14 of the medical vacuum device 10 and
The circumferential wall 110a of the rotary valve body 110 has a pressure transducer 150 that detects the suction pressure within the rotary valve body 110, and the peripheral wall 110a of the rotary valve body 110 has a cross-sectional area of communication that can be freely communicated with and disconnected from the rotary valve body 120 according to the rotation angle position of the rotary valve body 120. A suction port 112 that is open to the outside air side and a communication port 111 that is connected to the main suction pipe 14 side are bored, and a suction pressure signal from the pressure transducer 150 and a rotation angle detector 1 are provided.
The rotation angle position of the rotary valve body 120 is changed by driving the forward/reverse motor 130 whose rotation angle is controlled by the rotation angle signal from the main suction pipe 140, and the suction pressure in the main suction pipe 14 is kept constant by adjusting the communication cross-sectional area. A pressure regulating valve for medical vacuum equipment that maintains the pressure within the range.
