摘要:
A progressive modular distributor device for the division between a plurality of outlets of a lubricant fluid, said distributor including a first and a second base between which are sandwiched at least three distributor modules. The bases being interconnected by tie rods which pass through openings in the modules. A first surface of at least one of the modules presents at least one projecting part integral with the module. A second surface of a second of the modules, resting on the first, presents a corresponding housing in which the projecting part is inserted. The projecting part and the housing shaped to prevent reciprocal movement of the first and second module at least along an axis perpendicular to an axis of the tie rods when the projecting part is inserted in the housing.

The invention relates to a valve assembly which includes at least one, but typically two, balls located along a passage and which balls can be moved between open and closed positions to selectively control the passage of fluid along the passage. The valve assembly includes at at least one end thereof a retaining assembly which allows the effective sealing against one surface of a ball and retention of the same in position. A sealing assembly is also provided when two balls are provided, intermediate the same, which allows effective sealing to be achieved and at least one of the two trunnions which allows each of the balls to be mounted within the valve body is located only internally of the valve body. The components of the valve assembly which are located within the same can in one embodiment all be inserted into and located within the valve body from one common end.

Embodiments relate to valves comprising a member such as a plate or poppet, that is moveable relative to a stationary seat. The state of the member may be maintained against opposing forces with relatively little expenditure of energy. According to one embodiment, a poppet displaced from seating in the valve seat, may be held in position against opposing forces tending to close the valve, until a desired flow of gas through the valve has taken place. The poppet may then be released as desired, such that those opposing forces serve to passively close the valve. The valve may be secured in position utilizing mechanical, magnetic, electromagnetic, pneumatic, electrostatic, or hydraulic approaches. Valve embodiments may be particularly suited to controlling gas flows for compression and/or expansion in an energy storage system.

An encapsulated valve system includes a first housing portion having a first facing surface, the first facing surface comprising a plurality of branch pathways formed as a recess within the first facing surface. The valve system further includes a second housing portion having a second facing surface, the second facing surface comprising a plurality of branch pathways formed as a recess within the second facing surface. A disposable conduit is configured to be interposed between the first and second housing portions and disposed within the recess of the first facing surface and the recess of the second facing surface. The disposable conduit is thus sandwiched between the first and second facing surfaces. A plurality of pinch valve actuators are mounted on one or both of the first housing portion and the second housing portion, the plurality of pinch valve actuators configured to pinch the disposable conduit at selective branch pathways.

A valve assembly for the coolant system of an internal combustion engine including a housing, at least two coaxially disposed rotary valves journaled in such housing, each of such valves having an axially disposed fluid passageway communicable with an inlet port of such housing and at least one passageway communicating with the axially disposed passageway and communicable with an outlet port of the housing upon a particular orientation of such valve, and a drive gear operatively connected to such valves, operative to rotate such valves to different degrees.
摘要:
A valve assembly having a first valve defining an inlet connected to the inlet supply and an outlet connected to the concentrate chamber, a second valve defining an inlet connected to the permeate chamber and an outlet connected to the faucet, and a third valve defining an outlet connected to drain, a port connected to the concentrate chamber, and an inlet connected to the inlet supply. The port is selectively in fluid communication with the third valve outlet and inlet. When the faucet opens, the first valve opens, the second valve has permeate flowing, and the third valve opens a flowpath between the third valve port and the inlet due to pressure dropping in the second valve. When the faucet closes, the first valve closes and the third valve opens another flowpath between the third valve port and outlet due to pressure created in the second valve.
摘要:
A gas valve may include a valve body defining an upper valve seat region, and in some cases a lower valve seat region. A main valve that includes an upper main plate, and in some cases a lower main plate, may be disposed within the valve body. A control valve that includes an upper control plate, and in some cases, a lower control plate may be coaxially aligned with the main valve. The main valve may provide shut-off functionality while the control valve may provide flow control.
摘要:
A pressurization control device (10) for controlling positive pressurization of an electronic equipment enclosure, such as, for example, a telecommunications equipment enclosure (12 or 14), wherein the device (10) combines and integrates a number of valves or other control components and functions into a single, common valve body (28) or manifold providing a single, shared penetration point (54) into the enclosure (12 or 14), thereby advantageously minimizing the number of penetrations into and potential leakage points from the enclosure (12 or 14). The valves or other control components may be substantially conventional and may include, for example, a cable air tube connection fitting (30); a pressure cutoff valve (32); a pressure relief valve (34); and a static pressure valve or air stem (36); an express fitting (38); and an on/off valve (40).
摘要:
A remote pressure-controlled three-way valve device has a plunger axially traversed by an inlet passage normally closed by a spring-urged inlet valve. The plunger's outer sidewall has a recess in which an O-ring extends to abut against the steps of the recess to limit the plunger stroke and keep an outlet passage closed to a venting port formed in the sidewall of the body of the device. O-ring prevents short-circuits between the inlet passage and the vent port and a spring for counteracting friction between the O-ring and the device inner wall. Filters arranged in respective ports connectable to the input air-pressure supply and the tire inner tube provide fixed seats for the springs to bear on. The plunger may dwell in a stable intermediate position that opens the outlet or deflation passage is controlled by sending an air pressure through the inlet port at 50% of the normal pressure.
摘要:
A multi-port valve assembly for controlling the flow of fluid through a plurality of outlet ports. A valve housing defines a common inlet and a plurality of outlet ports. A valve member corresponds to each outlet port for controlling fluid flow through the respective port. Each valve member is independently adjustable for separately adjusting fluid flow characteristics through its respective port. All of the valve members are conjointly movable for controlling fluid flow through all the outlet ports simultaneously.
