A storage container having a base storage compartment configured to receive a divider by which the storage compartment is divided into two or more sub-compartments, wherein divider includes a tool configured to provide a secondary utility or function unrelated to dividing the storage compartment.

A timer-operated tap or timer cartridge for a device forming a timer-operated tap includes at least one opening for the inlet of the supply fluid and at least one opening for the outlet of the supply fluid. A main closure member is received in a main seat formed in at least one outlet or inlet opening to close the tap and is removed from the main seat to open the tap and allow the passage of the supply fluid between the inlet and outlet openings. Control means for controlling the movement of the main closure member by means of a control rod; and timer means intended for moving the main closure member into the seat thereof at the end of a given time interval preceding the removal thereof. An element forming an intermediate closure member and an associated intermediate seat may also be provided.

The invention relates to a method for controlling at least one first circulation pump (17b, 17c) of a heating or cooling system (1) having a primary circuit (2, 2a) and a secondary circuit (4, 30a) coupled therewith at a transfer point (3, 29). The first circulation pump (17, 17b, 17c, 17b) conveys a heating or cooling medium in the primary circuit (2, 2a), and in the second secondary circuit (4, 30a), at least one second circulation pump (12, 17d) is located that conveys a heating or cooling medium in at least one partial area of the secondary circuit (4, 30a). The volume flow rate (formula I) of the first circulation pump (17, 17b, 17c, 17b) is controlled in functional dependence on the volume flow rate (formula II) of the secondary circuit (4, 30) behind the transfer point (3, 29). In this way, a demand based, and thus an energy-efficient control of the primary-side circulation pump is achieved. The invention further relates to a pump system, comprising the at least one first and the at least one second circulation pump for carrying out the method.

It is provided a fluid flow control device for establishing a controllable fluid communication between an external fluid reservoir and a base pipe constituting part of a production string, as well as a production string and a method using such a fluid flow control device. The fluid flow control device comprises a primary flow path arranged inside a fluid control device housing, a secondary flow path and a movable valve element arranged at and/or within the primary flow path. The inlet of the secondary flow path is arranged separate from the inlet of the primary flow path.

A valve unit is moveably accommodated in a valve housing having a valve seat. A coil spring is provided at an outer periphery of the valve unit to bias the valve unit in an axial direction of absorbing a backlash between a driving-side screw portion of a driving portion and a valve-side screw portion of the valve unit. Pressure losses of fluid at respective portions are so made to satisfy a relationship of P0P1P2, wherein P0 is a pressure loss of the fluid passing through an outlet port, P1 is a pressure loss of the fluid passing through an axial space formed between the valve unit and the valve seat in a condition that the valve unit is most separated from the valve seat, and P2 is a pressure loss of the fluid passing through an axial gap formed between neighboring spring wire portions or passing through an axial gap formed between the coil spring and the valve seat.

A controller for an inline valve includes a manifold seating a set screw and has a reference fluid port, a control fluid port, and an actuator fluid port. A selector is movable within the manifold between a first position and a second position, the reference fluid port in fluid communication with the actuator fluid port in the first position, the control fluid port in fluid communication with the actuator fluid port in the second position. A biasing member is arranged between the selector and the set screw and urges the selector towards the first position. The set screw extends through an exterior of the manifold for adjustment of differential in pressures at the reference fluid port and the control fluid port responsive to which the selector moves between the first position and the second position. Inline valves and methods of controlling fluid flow through inline valves are also described.

The systems and methods of the present disclosure provides an independent passive variable resistor that can be interposed between a fluid reservoir at an inlet pressure and receptacle at an outlet pressure. The resistor can adjust resistance to the pressure difference from the input to the output so that the flow rate through it is a constant rate. The resistor can include a moveable element and a biasing mechanism located in a chamber to create a flow channel. Each side of the moveable element is exposed to the inlet and outlet pressures and moves within the flow channel to modify the resistance of the flow through the chamber in response to the pressures. The balance of these forces determines the position moveable element, which interacts with the fluid channel to determine the flow resistance through variable resistor. The biasing mechanism can provide the necessary pressure to establish equilibrium flow rate.

A bleed air selector valve allows selection and extraction of bleed air from a plurality of different engine bleed air ports to optimize engine efficiency and to maintain bleed requirements using a single line replaceable unit. The bleed air selector valve uses a relatively simple arrangement of poppets, check valves, and thermostatic compensation to augment high and low temperature to within acceptable limits. The bleed air selector valve significantly reduces weight, cost, envelope, and system complexity as compared to known two-port bleed systems with heat exchanger thermal compensation.

Disclosed is a valve having: a body that has an upstream end and a downstream end; an inlet orifice; a plurality of passages including: a first outlet passage extending into the body from the downstream end to a location intermediate the upstream end and the downstream end of the body; an inlet passage extending into the body from the upstream end of the body, the plurality of passages extending along mutually parallel axes, wherein the axes are offset radially and/or circumferentially from each other; and the inlet passage being formed in an insert configured for axially moving to: fluidly engage with the first outlet passage to define a continuous fluid passage between the upstream end and the downstream end of the body, wherein: an output flow rate through the body increases or decreases depending on an axial location of the insert.

A hydraulic control unit (4) includes a valve bush (12), a valve cover (15) partially closing the valve bush (12) on an end face (S1), a valve slide (13) guided in a longitudinal direction (L) within the valve bush (12), and a housing part (6).

A spring (14) is arranged within the valve bush (12) and preloads the valve slide (13) in a starting position. The valve bush (12) is inserted, together with the valve cover (15), the valve slide (13), and the spring (14), into the recess (8) of the housing part (6) and jointly form a hydraulic valve (9). The valve bush (12) forms an inlet (19), and the valve cover (15) forms an outlet (31).
