Abstract
The present disclosure is directed to a union bolt for reducing fluid pressure noise. The union bolt according to the present disclosure has a mounting chamber capable of accommodating a silencer therein, and the silencer is mounted in the mounting chamber. According to the present disclosure, the union bolt contains the silencer therein, so that the noise caused by fluid pressure can be reduced and the assembly efficiency of a fluid pressure line can be improved.
Claims10
A union bolt for reducing fluid pressure noise, the union bolt comprising:
- a fastening portion configured such that a male thread is formed on an outer surface thereof to be fastened to a first object having a first flow path through which fluid passes;
- a head portion configured to receive rotational force from a working tool so that fastening by the fastening portion is achieved;
- and
- a connection portion positioned between the fastening portion and the head portion, and provided with a connection hole connected to a second flow path of a second object having the second flow path through which fluid passes;
- and
- wherein the union bolt has a hollow flow path that is formed in a hollow shape extending from an end of the fastening portion to the connection portion and serves as a flow path connecting between the connection hole and the first flow path;
- and
- wherein the union bolt has a mounting chamber that is formed to expand from the hollow flow path toward the head portion and is shaped to accommodate a silencer for reducing noise.
