Abstract
In a compressed-air dryer, a base has formed therein a recess at the other end thereof. An inlet port is connected to an air compressor and communicates with the recess. An outlet port is connected to an air reservoir. Air after having passed through a desiccant container is discharged to the air reservoir through the outlet port. An oil-mist separator has one end thereof communicating with the inlet port through the recess. The other end of the oil-mist separator communicates with the desiccant container. The oil-mist separator is received within a tubular section of the base and cooperates with the tubular section to define a transport cavity therebetween. The inlet port communicates with the oil-mist separator thorugh the transport cavity and the recess.
Claims17
A compressed-air dryer for use in a pneumatic pressure circuit having an air compressor and an air reservoir, said compressed-air dryer comprising:
- a desiccant container having accommodated therein regenerable desiccant material:
- base means having formed therein a recess at one end thereof;
- inlet port means connected to said air compressor of said pneumatic pressure circuit and communicating with said recess;
- outlet port means through which air after having passed through said desiccant container is discharged to said air reservoir of said pneumatic pressure circuit;
- dump valve means arranged at said one end of said base means for causing said recess in said base means to communicate with the ambient atmosphere in response to a command from the outside;
- and
- an oil-mist separator arranged between said desiccant container and said dump valve means, said oil-mist separator having one end thereof communicating with said inlet port means through said recess therein, said oil-mist separator having the other end communicating with said desiccant container, in which said oil-mist separator removes oil in compressed air flowing from said air compressor toward said desiccant container through said inlet port means and said recess,
- wherein said base means has a tubular section, said oil-mist separator being received within said tubular section and cooperating with the latter to define a transport cavity therebetween,
- wherein said inlet port means communicates with the one end of said oil-mist separator through said transport cavity and said recess,
- a support member being arranged within said tubular section of said base means, for supporting said oil-mist separator, said support member having a tubular body which is concentric with said tubular section of said base means, said tubular body cooperating with said tubular section to define therebetween said transport cavity which is annular in shape, said oil-mist separator being received within said tubular body of said support member,
- fin means being arranged at said transport cavity, said fin means extending from said tubular body of said support member radially outwardly toward said tubular section of said base means perpendicularly to an axis of said tubular body, said fin means cooperating with an inner peripheral surface of said annular section and an outer peripheral surface of said tubular body to form said transport cavity into a continuous passage having one end thereof communicating with said inlet port means and the other end communicating with said recess, and
- wherein the compressed air introduced through said inlet port means flow along said continuous passage and is transported toward said recess.
