Abstract: A series of valves with tapered-conical seats including valves such as safety relief or self-regulating in-line check valves which operate without springs but by the use of self-holding tapers which firmly stay in place when seated, the angle of the taper varying between 0.5.degree. to 45.degree., depending on the kind of material chosen and the valve type, TEFLON requiring a smaller angle for the same pressure holding capacity as conventional materials or other plastics, offering also valve design variations which include novel relief valves with springs and with self-relieving tapers, as well as shutoff valves with self-holding and self-relieving tapers operated by solenoids directly, and piloted valves, the valve series with conical seats, and improved sealing characteristics reduces dribble range while reference load is self-holding taper or a spring, and allows for reusable valves to replace safety rapture discs in some applications.

Abstract: Simple 2-way, 3-way and 4-way poppet valves employ thermo-electric operators in lieu of solenoid operators to shift poppet stem inside valve housing for a position change when operator is electrically energized thereby producing heat which creates high internal operator pressure by a working fluid housed therein to enable exerting a force over its movable end in contact with valve stem causing the shift of the stem and the subsequent valve operation wherein disconnecting the electric power to the operator results in the elimination of the end thrust to the stem end operator exerted allowing for stem to assume the desired position.

Abstract: Automatically Self-Reciprocating sequencing valve for use with pneumatic power cylinders/actuators in systems operated at frequencies of a few cycles to a few thousand cycles per minute comprises a valve housing with a central bore adaptable to receive a shuttle member that makes or breaks fluid communication between a fluid supply source and a receiver such as a power cylinder or an actuator of a positive displacement pump in response to fluid pressures acting over surfaces such shuttle member entails as controlled by appropriate slave valve housed alongside therein including fluid supply and exhaust ports entering and leaving said valve housing, and together with said slave valve allowing an automatic reciprocating-valve-operation for as long as the pressurized fluid is supplied thereto to result in self-reciprocating operator responsive to not only system pressures for cycle regulation but also to an externally provided biasing flow regulator for an easy control of cycle frequencies within the desired prac

Abstract: A reciprocating device for proportionating volumes of two distinct and different fluids within the same housing by a simultaneous fluid drawing from a supply source into the separate compartments provided inside an elongated housing of differential diameters having separating seals incorporated therein and receiving slideably different diameter pistons of elongated close sliding fit, comprising separate chambers suitable for fluid separation and holding therein at the end of a first suction cycle and subsequently by a simultaneous fluid discharge from the separate chambers for mixing with resultant dilution thereof during a second exhaust cycle, to provide simple and accurate proportioning-diluter adaptable for use in applications handling highly concentrated chemicals in a solution form subject to a precise dilution in fixed measured displacements per each stroke, including various means of diluter operation from manual to automatic unit operation by the use of pressurized fluids such as pressurized air or e

Abstract: A pressure reducing valve for use with compressed gas containers requiring fixed volumetric flow at regulated exhaust pressure regardless of pressure variation inside said container changing from initially high pressure value to eventually low final pressure value, consists of a spring loaded metering valve directly responsive to pressure load with a valving element comprising a needle inside control orifice for control of small quantity flow as regulated by relatively long conical stem travel, and a main valve of pin configuration inside valve nozzle exhaust port at one end subjected to pressurized gas for maintaining valve bubble tight shut, and at the other end protruding said exhaust port for valve actuation externally by pin depression for initiation of flow which terminates automatically when such depression is removed rendering valve closed and bubble tight by the pressure action over pin end exposed to compressed gas pressure, including a safety valve with self-locking tapers in valve seats and a pres

Abstract: An intensifier for use with pressurized fluids requiring additional pressure boosting to assume higher presures includes an elongated housing with differential diameter internal bore of which large end is closed by a cap with fluid port therein and the opposite small end provided with an end wall having fluid passage therethrough, a differential diameter elongated piston of close sliding fit inside the bore having small plugging piston end at one end and a large actuating piston end at the other end with an intermediate diameter intensification piston therebetween and capable of being shuttled inside housing bore from first small piston end engaged position preventing pressurized fluid supply to the intensification chamber to the second small piston disengaged position allowing fluid supply thereto while simultaneously developing an evacuated annulus inside intensifier with a vacuum force tending to maintain piston in the first position and aiding in the operation of intensifier through an airless void when a
