A modular valve system having fixed valve ports with frame openings on the exterior of each port. Corresponding connectors or plugs are designed to fit within the valve ports and be locked in place by a clip passing through the framed openings and around the connector or plug. The internal valve component may be electrically or mechanically controlled. The modular valve system may be connected to a vehicle coolant system to control fluid flow to a heat exchanger or bypassing the heat exchanger.

The disclosure relates to valve assemblies having a valve body including a first port, a second port and a fluid passageway extending therebetween. A valve member, having a through port, is arranged in the fluid passageway and is moveable between an open and closed positions. A sealing arrangement is arranged between the first port and the valve member and includes a sealing member arranged to seal against the valve member such that fluid cannot flow around an outer surface of the valve member. The sealing arrangement includes a sleeve arranged in the fluid passageway between the first port and the valve member. A deformable, incompressible, medium is contained around the sleeve and arranged such that, in use, a fluid within the sleeve exerts an outward pressure on the sleeve causing the sleeve to deform and act on the medium to push the sealing member against the valve member.

A refrigerant control valve apparatus includes a valve body provided with a main control valve controlling the refrigerant sent to a discharge port and a temperature sensing control valve controlling supply and discharge of the refrigerant to a temperature sensing chamber. A fail-safe mechanism is provided which supplies the refrigerant to the discharge port in a case where the temperature of the refrigerant exceeds a set value. The temperature sensing control valve is set in an open posture in a case where the main control valve is in a closed posture that closes the discharge port and the temperature sensing control valve is set in a closed posture in a case where the main control valve is in an open posture that opens the discharge port.

The rotary valve device includes a valve 30, a housing H having a joining surface 14b.sub.1 located at ends of a fitting hole 14a and a through hole 16, a thermostat 110 partially accommodated in the through hole 16, a cylindrical seal member 80, an urging spring 90, and a passage member 60. The passage member 60 includes a cylindrical holding member 61 that is fitted into the fitting hole 14a and holds the cylindrical seal member 80 and the urging spring 90, and a connector member 62. The connector member 62 includes an annular fitting recess 62a.sub.3 into which a part of the cylindrical holding member 61 is fitted, and a detour passage 62a.sub.4 that is divided from the fitting recess by a wall portion to partially accommodate the thermostat and bypasses the cylindrical seal member to communicate with the through hole.

A ball drain wye strainer valve assembly includes a wye strainer located adjacent to a T-ball valve within a unitary body. The ball drain wye strainer valve assembly includes an additional valve member. The combination of the valve members permits the flushing of the wye strainer screen from either upstream or downstream. A drain is also incorporated to allow for the system draining, flushing, or air-purging during the initial installation and subsequent maintenance of the screen and wye strainer.

A seal arrangement for use in a fluid control valve includes: a first seal configured to sealingly abut against an actuatable valve body of the fluid control valve; a second seal configured to sealingly abut against a valve housing of the fluid control valve; and an elastically deformable intermediate spacer, arranged between the first seal and the second seal and configured to elastically space the first and second seals apart. At least in an installed state of the seal arrangement in the fluid control valve, the first seal and the second seal are joined to one another in positively locking fashion in an axial direction of the seal arrangement.

A rotary valve has a valve plug that is rotatable in a valve body about a rotational axis. Surface features of the valve plug and surface features of the valve body cooperate to provide a bearing by which the valve plug is rotatably supported with respect to the valve body. In addition, each of the valve plug and the valve body include a plurality of annular projections that encircle the plain bearing and axially overlap one another so as to form a labyrinth that surrounds the bearing. The labyrinth forms a fluid path that collects abrasive particles suspended in the fluid passing through the valve, whereby wear of the valve is reduced.

A cross hole deburring tool which performs rotary cutting on a cross hole burr occurring on a cross ridgeline part between a through path and an inner circumferential surface of a spherically-shaped hollow part. A tool main body includes a tip part and a shank, and the tip part has a shape obtained by setting a diameter axis of a circle, setting an eccentric axis parallel to the diameter axis and away therefrom by a predetermined eccentric distance, setting a closed region in a bow shape formed of a line segment obtained by cutting the eccentric axis by the circle and a minor arc on the circle by defining this line segment as a chord, setting an outer surface shape of a bow-shaped solid of revolution formed by rotating this bow shape about the eccentric axis, and taking this outer surface shape as the shape of the tip part.

A heating installation or cooling installation mixing device has a valve housing (14) including a first flow path from a first connection (A-B) to a second connection (A), and a second flow path from the first connection (A-B) to a third connection (B). A movable valve element (24), arranged inside the valve housing (14) in the flow paths, is configured to vary a ratio of cross sections of the flow paths. A valve element drive (36) is arranged on the valve housing (14) and includes an internal control device (38) for movement control of the drive (36) and includes a first communication interface (44) for external control device (40) communication and a second communication interface (46). An internal sensor (48, 50) is arranged in or on the valve housing (14) and is connected to the first communication interface (44) for transmitting a sensor signal to the external control device (40).

The invention relates to an apparatus (100) for handling fluid of an at least partially electrically powered vehicle, comprising a substantially plate-shaped base element (110) defining a base plane, the base plane separating a first subspace (210) from a second subspace (220), at least a first fluid flow channel section (115) which is largely located in the first subspace (210), and at least one second fluid flow channel section (125) which is largely located in the second subspace (220), wherein the base element (110) comprises at least one first flow-through opening (130) fluidly connecting the first fluid flow channel section (115) to the second fluid flow channel section (125).

Further, the invention relates to a method of manufacturing an apparatus (100), comprising the steps of providing the base element (110) with at least a first fluid flow channel section (115) and a first flow-through opening (130), and placing the second fluid flow channel section (125) in the second subspace (220) against the base element (110), thereby fluidically connecting the first fluid flow channel section (115) to the second fluid flow channel section (125).
