Abstract
A fluid powered mechanism has a housing with a generally cylindrical shape and circumferentially adjacent axially extending primary and secondary fluid passageways. Exhaust direction and rotary limit speed are controlled by a flow reversing and regulating ring having a first face with a thru slot and an adjacent blocking flange and a second face having a turning flange which is the reverse of the blocking flange of the first face. The flow reversing and regulating ring is color coded to indicate the size of the fluid flow passageways and, thus, the limit speed provided by the ring. The rotational limit speed and the exhaust direction are determined by selection of the color-coded flow reversing and regulating ring and by its orientation in the tool.
Claims21
A flow reversing assembly for control of exhaust fluid flow for a fluid mechanism comprising in combination:
- a mechanism housing having circumferentially adjacent and axially extending primary and secondary fluid passageways;
- a control ring member having two opposed faces comprising:
- a first face having a thru slot in fluid communication with said primary passageway and a circumferentially adjacent blocking flange;
- and
- a second face having a turning flange to direct exhaust flow to said secondary fluid passageway such that said turning flange is the reverse of said blocking flange.
An exhaust flow reversing member for a fluid mechanism comprising:
- an annular ring having two opposed faces;
- a first face having a flow thru slot and a circumferentially adjacent flow blocking flange;
- and
- a second face having a flow turning flange such that said turning flange is the reverse of said blocking flange.
An annular ring member in a fluid mechanism for regulating the fluid flow comprising:
- means defining an orifice in said annular ring member in the fluid flow path having a predetermined area and configuration so as to create fluid back pressure in the fluid flow path;
- said annular ring member further comprising two opposed axial faces such that:
- a first face has a flow thru slot and a circumferentially adjacent flow blocking flange;
- and
- a second face having a flow turning flange wherein said flow turning flange is the reverse side of said flow blocking flange.
