Abstract:
A flow control valve comprising:a valve housing having an inlet port and at least first and second outlet ports therein; anda cock plug body that is rotatably arranged in said valve housing so as to be rotatable about a rotation axis, and that has a flow passage including an inflow portion and a first outflow portion therein, and that has first and second pre-flooding passages extending from said flow passage to positions rotationally displaced to opposite sides of said outflow portion of said flow passage;wherein:said inflow portion of said flow passage and said inlet port are arranged in communication with each other, and each respectively extend in a direction that is at least substantially parallel to said rotation axis;said outflow portion of said flow passage and at least a respective radially inner end of each said outlet port respectively each extend substantially radially relative to said rotation axis;said outflow portion of said flow passage and said outlet ports are so arranged relative to each other so that said outflow portion of said flow passage communicates with said first outlet port and not said second outlet port when said cock plug body is in a first rotational position about said rotation axis, and so that said outflow portion of said flow passage communicates with said second outlet port and not said first outlet port when said cock plug body is in a second rotational position rotationally displaced from said first rotational position about said rotation axis; andsaid pre-flooding passages are so arranged relative to said outlet ports and said outflow portion of said flow passage so that said first pre-flooding passage communicates with said second outlet port and said outflow portion communicates with said first outlet port when said cock plug body is in a first intermediate rotational position between said first and second rotational positions, and so that said second pre-flooding passage communicates with said first outlet port and said outflow portion communicates with said second outlet port when said cock plug body is in a second intermediate rotational position between said first intermediate rotational position and said second rotational position.
