Definitions
- Maslousky Attorney-Mahoney, Miller & Stebens ABSTRACT An actuator valve system for a two-stage fluidoperated unit in which a main pilot-operated valve controls the supply and exhaust of fluid to the unit and the positioning of the valve is controlled by a pilot control sleeve which is operatively connected to the valve to apply actuating fluid pressure thereto and, in turn, is positively axially moved to its different positions mechanically by movement of the fluid-actuated unit with which it is cooperatively positioned.
- FIG. 5 is a transverse sectional view taken along line 5-5 of FIG. 3.
- the sleeve 29 is of an axial extent substantially less than that of the axial spacing-of the pistons 12 and 13, but greater than the spacing of the heads'25 and 26, so that the sleeve will always project into one or both of the actuating chambers 18 and 20.
- the main valve 10 illustrated is of the spool type and comprises a housing 40 having a valve sleeve 41 fixed in a bore extending completely therethrough with a valve spool 42 slideably mounted in the sleeve.
- a connection 43 is provided for receiving an actuating fluid, in the form of compressed air from a suitable source of supply and for supplying it in to a passage 44 in the valve housing leading to opposite ends thereof and connecting to an orifice 45 at one end and an orifice 46 at the other end which lead into the opposite ends of the valve sleeve 41.
- the housing 40 is provided with five passages, 51, 52, 53, 54, and 55, which are connected to the, interior of the valve sleeve 41 at axially spaced intervals.
- the fluid supply passage 44 connects intermediate its end with the passage 51 which surrounds the valve sleeve 56.
- an actuator valve system for a double-acting fluidoperated work unit which can use various commercially available pilot-operated four-way valves.
- the positioning of the four-way valve which, in turn, controls the stroke of the to alternately receive actuating pressure and have the pressure vented therefrom to reciprocate the cooperating work members, said work members being connected together for simultaneous movement by a shaft, an actuating valve system for alternately supplying actuating fluid pressure to one.
- said valve system comprising a main four-way control valve having passages connected to said chambers and to exhaust and having a pilotcontrolled movable valve member for selectively connecting said passages to alternately supply actuating pressure to one of the said chambers while exhausting it'from the other, means for continuously supplying pilot pressure to said valve which can be controlled to move said valve member in opposite.
- control means for controlling the pilot pressure to move said valve member as the reciprocable work members and connecting shaft near the end of their stroke in' either direction so as to reverse the stroke
- said control means comprising a control sleeve surrounding said shaft and slidably' mounted thereon and having opposed ends which are exposed at said opposed actuating chambers, said sleeve being mounted for slidable movement in a surrounding adapter hav-. ing pilot fluid exhaust passages connected to said valve, said sleeve having passages which, upon reciprocation thereof, al-i ternately connect said pilot exhaust passages to vent openings in said adapter so as to move said valve member in accordancewith the movement of said work members to reverse move-: ment thereof.
- said adapter includ-i ing a bearing portion surrounding said sleeve and having the, pilot fluid exhaust passage form therein, said pilotfexhaust;
