A connection arrangement for filling and draining a liquid includes a sealing element arrangement and a joining arrangement. The sealing element is movable between a closed position and an open position. A filling passage of the connection arrangement is defined by at least one of the sealing element arrangement or the joining arrangement. A draining passage of the connection arrangement is definable by the sealing element arrangement and the joining arrangement, the draining passage being adjustable by moving the sealing element arrangement between the closed position and the open position.

A first-pump arrangement flow path, temperature-adjustment target-device arrangement flow paths, and a second-pump arrangement flow path are connected to a communication flow path in this order from one end side to the other end side of the communication flow path. A first heat exchanger is disposed in the first-pump arrangement flow path among numerous flow paths, which is connected to the communication flow path at a position on a side of the first-pump arrangement flow path, rather than the flow path in which a second heat exchanger is disposed. The switching portion is operated to establish communication between plural flow paths, starting from the flow path connected to the communication flow path at the position closest to the one end side among the numerous flow paths, up to the flow path connected to the communication flow path at an n-th position counted from the one end side among the numerous flow paths.

Improved fluid supply assemblies for fluid systems are provided. In exemplary embodiments, the present disclosure provides for improved fluid supply assemblies and related features, systems and methods of use. More particularly, the present disclosure provides for advantageous faucet assemblies (e.g., electrically or mechanically actuated faucet assemblies) having an integrated anti-scald device and having an integrated temperature mixing valve. The present disclosure provides for a faucet assembly having an integrated temperature mixing valve, and/or having an integrated anti-scald device configured to stop the inlet flow of hot water in the event the mixed outlet water temperature exceeds a user-selected set point. Advantageous faucet assemblies of the present disclosure can prevent scalding as defined by ASST; 1070, Improved, convenient and effective systems and methods for utilizing improved faucet assemblies in fluid systems are provided.

A greywater control valve includes: a housing having an input port and at least two output ports; and an insert including a port connection element and a vent. A rotary greywater control valve includes: a housing including: an input port; a first output port; and a second output port; and an insert that rotates within the housing, the insert including: a connection channel that couples the input port to one of the first output port and the second output port; and a vent channel that couples the connection channel to one of the output ports. A fluid control valve includes: an input port located along a first axis; a first output port located along a second axis that is perpendicular to the first axis; a second output port located along the second axis; and a fluid channel that selectively couples the input port to one of the output ports.

Low head loss systems are detailed. The systems may include chambers having low impedance to water flow therethrough and repositionable gates or other valves within the chambers. The valves may direct water as a function of whether an associated heating device is active. At least some gates may incorporate poppet valves or other high-flow by-passes.

A hydraulic valve assembly (1) with a housing (18) and with a spool (2) which is rotatable in the housing (18). The spool comprising a pressure supply orifice (3) and at least one clutch actuating orifice (4, 5) which is connectable to a clutch actuating cylinder (6, 7). The spool (2) comprises a pressure release orifice (8) which is arranged at the spool (2) so that the pressure release orifice (8) is closed by rotational movement of the spool (2) while the clutch actuating orifice (4, 5) is opened by such rotational movement. The invention further relates to a clutch actuating device with such a hydraulic valve assembly (1) and a corresponding marine propulsion system.

A high-pressure switching valve includes a stator and a rotor. The stator includes a plurality of ports where each port is connected at one end to a port connection and having at another end a predetermined port opening cross section at a stator end face of the stator. The rotor includes a rotor end face and at least one or a plurality of grooves. The rotor can be configured to have a rotary position with respect to the stator where two predetermined port opening cross sections connect to one of the grooves in a pressure-tight manner. The rotor and the stator can be pressed together in a sealing manner at the rotor end face and the stator end face in regions away from the port opening cross sections and the at least one or a plurality of grooves. The rotor and the stator each include a hard material. The rotor can be configured to wobble or tilt with respect to a rotational axis of the rotor.
