Abstract
An air compressor comprises a compressor that compresses introduced air and a tank that stores the compressed air generated by the compressor. The air compressor also comprises a discharge pipe from which the compressed air and a condensate in the tank are discharged to an outside of the tank. The air compressor also comprises a drain cock that is disposed in a passage of the discharge pipe and serves to open and close the discharge pipe. The air compressor also comprises a discharge pipe end portion that includes a discharge port facing upward at a tip end of the discharge pipe. The air compressor also comprises a tubular cover including a top portion that covers the discharge pipe end portion from above.
Claims16
An air compressor, comprising:
- a compressor configured to compress air;
- a tank configured to store compressed air from the compressor;
- a discharge pipe (i) configured to discharge the compressed air and a condensate in the tank to an outside of the tank and (ii) having a discharge pipe end portion including a discharge port facing upward at a tip end of the discharge pipe;
- a drain cock that is (i) within a passage of the discharge pipe and (ii) configured to open and close the discharge pipe;
- a tubular cover including (i) a top portion that covers the discharge port from above and (ii) an opening that faces downward;
- a lower cover that covers the opening of the tubular cover;
- and
- a muffling member that is housed within the tubular cover so as to surround an outer circumference of the discharge port of the discharge pipe end portion;
- wherein:
- the lower cover includes (i) a support portion that is configured to support the muffling member from below, (ii) a plurality of protrusions that form the support portion and protrude upward and (iii) a plurality of discharge grooves;
- and
- each of plurality of discharge grooves is between adjacent protrusions of the plurality of protrusions and is configured to guide the condensate in an outer peripheral direction.
