A valve assembly for controlling cooling fluid flows in a motor vehicle, the valve assembly including: a valve housing having a main housing body and a housing cover connected to the main housing body, a valve body receiving space being developed in the valve housing, which is enclosed by the main housing body and the housing cover, a fluid line system having at least two fluid lines, which run in different spatial regions starting from the valve body receiving space, a valve body, which is accommodated in the valve body receiving space rotatable about an actuation axis, the valve body being designed to taper along the actuation axis in such a way that by rotating the valve body about the actuation axis, a fluid connection situation of at least two fluid lines of the fluid line system is changeable, and a prestressing means, which applies a pressure onto the valve body along the actuation axis in the tapering direction,
both the valve body as well at least the main housing body to be formed as injection molded parts from thermoplastic.

A rotary valve, comprising a valve housing with a valve chamber, wherein the valve chamber has a chamber wall in which at least two fluid openings are provided, wherein the valve chamber has a receiving opening on the end face side, wherein the valve chamber accommodates a valve core, wherein the valve core is provided with a channel structure which interacts with the fluid openings, wherein the valve core is supported in the valve chamber in a rotationally movable manner, wherein the valve chamber is formed in a conical shape.

The exhaust gas recirculation (EGR) system provided herein utilizes a crossover (X) valve that is selectively activated at the direction of the electronic control module (ECM) to mix the high temperature (HT) and low temperature (LT) circuits of the EGR system under certain predetermined operating conditions. Thus, HT circuit fluid (at engine temperatures) is selectively fed into the LT circuit fluid (at ambient temperatures) to heat certain LT circuit components that are normally cooled by the LT circuit before starting the low pressure (LP) EGR in certain cold cycles. When this heating is finished, the X valve is closed to provide normal HT circuit/LT circuit fluid separation. The X valve can be controlled using a rotational actuator or the like. To avoid exposing the LT circuit to the high revolution-per-minute (RPM) operating conditions of the HT circuit, a HT bypass mechanism is provided.

A rotary valve includes a valve body including an opening formed therein, a rotary component received within the opening of the valve body with the rotary component configured to rotate relative to the valve body about an axis of rotation thereof, and a sealing assembly including a hard sealing structure and a soft sealing structure disposed between the valve body and the rotary component. The hard sealing structure is formed from a substantially rigid material and is configured to sealingly engage the rotary component. The soft sealing structure is formed from a resiliently deformable material and is configured to sealingly engage the hard sealing structure and the valve body.

A diverter valve for conveying a material has a housing with at least three passage openings for feeding or discharging material. The passage openings define a conveying plane. The diverter valve includes a rotary part with an outer contour that is conical, at least in sections, with respect to its axis of rotation. The rotary part is arranged in a sealed manner in the housing. The rotary part can be axially displaced and rotated within the housing. The axis of rotation is perpendicular to the conveying plane. A passage conduit is arranged in the rotary part, which, depending on the rotational position of the rotary part, connects to each other two passage openings for conveying material along the passage conduit through the diverter valve. A drain opening is provided in the housing for the automatic drainage of a liquid from the housing.

A valve assembly for select distributed discharge of received fluid in a predetermined manner is generally provided. The assembly includes a manifold and a rotatable valve body. The manifold has an internal chamber, a fluid ingress passage for receipt of fluid, and a plurality of fluid discharge conduits. The fluid ingress passage and fluid discharge conduits are in fluid communication with the internal chamber. A first internal chamber section is characterized by the fluid ingress passage with a second internal chamber section characterized by ingress portions of the fluid discharge conduits. The valve body is adapted to be sealingly seated within the internal chamber so as to fluidly isolate the internal chamber sections, and includes a bore axially extending inwardly from a first end thereof for receipt of fluid from the fluid ingress port of the manifold, and a fluid egress passage in fluid communication with the bore for passage of received fluid to a select fluid discharge conduit of the fluid discharge conduits.

A diverter valve for conveying material to be conveyed, the diverter valve being cleanable using a method for CIP cleaning, comprises a housing with at least three passage openings to feed or discharge the material to be conveyed, the passage openings defining a conveying plane. The diverter valve further comprises a rotary part having an axis of rotation and an outer contour designed conically in relation to the axis of rotation at least in sections, the rotary part being arrangeable in the housing in a sealed manner, the rotary part being displaceable along the axis of rotation in an axially driven manner and being arranged such as to be drivable for rotation about the axis of rotation, the axis of rotation being oriented perpendicular to the conveying plane, a passage duct arranged in the rotary part, which—depending on a rotary position of the rotary part—connects in each case two passage openings for conveying material along the passage duct through the diverter valve. The CIP cleaning method of a diverter valve of this type comprises the pulling back and rotating the rotary part into an intermediate position to clean and then dry the diverter valve intensively. A particular feature is the embodiment configured without drainage in the housing of the diverter valve.

A diverter/mixing valve is provided that includes a main outer housing and a barrel assembly disposed inside the main outer housing. When actuated, an actuator rotates the barrel assembly between an open end inlet position where a first fluid stream flows into a first inlet port and a second fluid stream is blocked from flowing into a second inlet port, and an open side inlet position where the second fluid stream flows into the second inlet port and the first fluid stream is blocked from flowing into the first inlet port.
