A valve, which is rotated about a rotational axis, includes a valve outer peripheral portion. The valve outer peripheral portion has a valve inflow port for supplying fluid to a flow passage of the valve outer peripheral portion and valve outflow ports for discharging the fluid from the flow passage. The valve outflow ports include: a main outflow port which is configured to communicate with a whole of a seat opening of a valve seat; and a plurality of intermediate outflow ports, each of which is configured to communicate with a portion of the seat opening. An axial dimension of each intermediate outflow port, which is measured in an axial direction of the rotational axis, is smaller than an axial dimension of the seat opening, which is measured in the axial direction. The axial dimension of each intermediate outflow port is progressively changed in a circumferential direction.

The present disclosure discloses a seal and a regulating valve having the seal. The seal is used for sealing a flow channel between a pipe orifice of a housing and a valve body in the regulating valve. The seal includes an elastic member and an embedded member. The elastic member is ring-shaped, the embedded member is at least partially embedded in the elastic member, and the hardness of the embedded member is greater than that of the elastic member. The seal of the present disclosure has a simple structure, which not only enables miniaturization of the structure of the regulating valve, but also can simplify assembly steps of the regulating valve, thus facilitating assembly automation of the regulating valve.

The cooling system also includes a bypass valve connected downstream of the coolant pump, the bypass valve configured to close a fluid path that connects the coolant pump and the liquid-to-liquid heat exchanger.

A solenoid valve for the automotive industry includes a housing comprising an inlet channel and an outlet channel. An electromagnetic circuit is arranged in the housing. The electromagnetic circuit includes a coil wound onto a coil carrier, an armature, a core, and a return device. The armature and the core are arranged in a valve interior. A valve rod is arranged to adjoin the armature. The valve rod is movably mounted in the core via a bearing. A sleeve body seals the valve interior. The sleeve body is provided as a bearing element for the armature. A valve closure body is operatively connected to the armature. The valve closure body includes pressure equalization openings and is movably mounted in the sleeve body via a first sealing element. A spring pre-tensions the armature.

An apparatus for regulating the coolant flow for internal combustion engines in motor vehicles has a valve body which can be moved in a valve apparatus (8) for opening or closing or partially opening. The valve body can be arranged in a throughflow opening to be connected to a brake system (1, 2, 3, 4; 11, 12, 13, 14; 21, 22, 23, 24, 25) to regulate the volume of the coolant flow.

A system includes an engine defining a water jacket fluidly coupled to a heat exchanger. An exhaust manifold defines an exhaust manifold cooling passage. A pump is fluidly coupled to the water jacket, and to each of the heat exchanger and the exhaust manifold cooling passage. An engine cooling circuit includes the water jacket, the heat exchanger, and the pump. An exhaust cooling circuit is selectively fluidly coupled to the engine cooling circuit. The exhaust cooling circuit includes the water jacket, the exhaust manifold cooling passage, and the pump. A control valve includes an inlet fluidly coupled to a first portion of the water jacket. A first outlet is fluidly coupled to a second portion of the water jacket. A second outlet is fluidly coupled to the exhaust cooling circuit. The control valve is structured to selectively control flow of coolant fluid through the second outlet.

A cooling circuit for a vehicle includes a single cooler, a refrigeration machine, a first heat-generating device, a second heat-generating device, a coolant pump arrangement configured to pump a coolant, a valve arrangement, and an electronic control module. The first heat-generating device requires the coolant at a first coolant temperature level. The second het-generating device requires the coolant at a second coolant temperature level. The valve arrangement is configured to supply the coolant from the first and second heat-generating devices to the refrigeration machine and/or to the single cooler. The electronic control module is designed to control a temperature of the coolant at coolant inlets of the first and second heat-generating devices by varying flow rates of the coolant through the refrigeration machine and/or the single cooler.

A coolant control valve, including: a housing with a first port and a second port; a primary rotary valve disposed within the housing and including a primary body; and a secondary rotary valve disposed within the housing and including a secondary body. The primary rotary valve and the secondary rotary valve are rotatable around the axis of rotation by at least one actuator to a first configuration. In a first configuration of the primary rotary valve and the secondary rotary valve around the axis of rotation: a first straight line, orthogonal to the axis of rotation, passes through the primary body and the first port; and a second straight line, orthogonal to the axis of rotation and co-planar with the first straight line, passes through the secondary body and the second port.

An apparatus for handling fluid within an at least partially electrically driven vehicle, with a valve device including a valve housing. The valve housing includes at least three two radially arranged port openings and at least one axially arranged port opening for the inflow and/or outflow of fluid, and a valve body which is arranged inside the valve housing and is configured to be rotatable about an axial axis of rotation R.
