Abstract: A valve means for controlling a linear or rotary hydraulic motor, which is connected to a pump (P) acting as pressure medium source via the valve means, and to a tank (T) either directly or via a valve means. Known valve means of this kind comprise valves with valve slides, which control both the supply of pressure medium to the motor and the return flow from the same. These valves, however, do not always satisfy the demand in question, owing to internal leakage which, for example, implies that a linear motor is caused to carry out undesired movements.The present valve means, however, comprises at least one seat valve (C) located in a main flow connection between the pump (P) and one port (A) of the motor, where each seat valve (C) for adjusting the flow in the main flow connection to the motor (1) is controlled by a pilot flow, which is adjustable by a pilot valve (E) and originates from the main flow through the seat valve (C), and which after the pilot valve (E) returns to the main flow at a point after the seat valve (C), seen in the flow direction.

Abstract: A pneumatic valve is disclosed, for controlling the position of a ram in a partly-extended condition. The valve has a combination of rubbing seals and diaphragms, for smooth operation and reliability. A spring-loaded plunger presses the diaphragm against the mouth of a port, to seal off the port. A piston with rubbing seals lifts the plunger from the diaphragm, to open the port. The piston seals rub against plastic, for freedom from water contamination problems, while the diaphragm provides the high integrity seal needed to control the ram position. A particular application of the valve is to the air control of dentist's chair, medical table or medical chair.

Abstract: A fluid control system for controlling a fluid motor (12) wherein a pressure regulating pilot valve (10) controls a directional control valve (11) by manipulation of handle (21) associated with the pilot valve (10). The directional control valve (11) includes a make-up valve (84). The pilot valve (10) includes a spool (26) having a recess (98) providing selective communication between the backside of the movable valve member (86) of the make-up valve and an exhaust recess (100) communicating with the reservoir tank (36). A direct mechanical connection is provided from the handle (21) to the spool (26) as the result of an abutment of an upper end portion (102) of the spool (26) with a surface (49) on the plunger (28) engaged by the control handle in effecting the positive movement of the spool (26) to effect the desired communication between the recess (98) and recess (100). The spool normally is resiliently movable to effect a desired pressure regulation fluid flow through the pilot valve (10).

Abstract: A fluid flow control device suitable for controlling the flow of fluid between two chambers of a jack comprises a valve between each of the two chambers being controlled and a common chamber. The valves are controlled by pilot operated stops which, when retracted permit the valves to close fully but which, when extended hold the valves partially open. A source of make-up fluid can be connected to the common chamber, and the feed to the pilot valves can be tapped off the common chamber by way of a restriction. Alternatively, the pilot valves can be isolated from the common chamber and a separate source of pilot fluid provided. In this case, the common chamber can be permanently connected to a source of fluid under pressure which can be a fluid pressure accumulator.

Abstract: A direction control valve for controlling a reversible hydraulic actuator includes a valve body in which a pair of valve stems and a pair of float control pistons, respectively axially aligned with the valve stems, are reciprocally mounted. To establish a float condition in the actuator, the pair of valve stems are simultaneously shifted to respective active positions by engagement of the pair of float-control pistons to which pressure fluid is routed upon selective energization of a solenoid-operated valve by manually closing a first normally open switch. A second normally open switch is connected in parallel with the first switch and is closed by a switch-control piston mounted in the valve body between and in fluid communication with the float-control pistons and shiftable concurrent therewith whereby the manually operable switch may be released without effecting de-energization of the solenoid-operated valve. A control rod is rockably mounted in the valve body for selective movement to opposite sides of a neutral position for respectively initiating independent shifting of the pair of valve stems to their active positions for respectively effecting extend and retract conditions in the actuator. A cam is fixed to the control rod and is operable, when the control valve is in its float-effecting condition and the control rod is moved from its neutral position, to move the switch-control piston to release the second switch and de-energize the solenoid-operated valve whereby the control valve is released from its float effecting condition.

Abstract: Four poppet valves are mounted in a common machined body which has a single inlet port, a pair of working ports and a pair of exhaust ports. The body interior has four valve ports, two of which connect the inlet port to the two working ports and the other two connecting the working ports with the exhaust ports. The housing also has identically sized guide supports and piston chambers for the poppet valves. These may be chosen either as normally closed or normally open straight way valves in a variety of arrangements. With each arrangement one or more pilot valves, either straight way, three-way or four-way, normally closed or normally open, may be connected to the piston chambers. Thus, the valve system may be arranged to have a four-way function as controlled by a single normally closed three-way pilot valve, operate two independent fluid motors using two three-way pilots, or can be arranged for various other control functions.
