摘要： An engine housing includes a rotor housing and a side housing assembly. The rotor housing includes a rotor housing body. The rotor housing body extends about an axis to form a rotor cavity of the engine housing. The rotor housing body extends between and to a first axial end and a second axial end. The side housing assembly includes a side housing body, a side plate, and a seal assembly. The side housing body is disposed at the first axial end. The side plate is disposed axially between the rotor housing body and the side housing body. The side plate includes an inner side, an outer side, and a perimeter edge. The seal assembly includes a support ring and a sealing ring. The support ring is disposed at the perimeter edge and the first axial end. The support ring circumscribes the side plate. The sealing ring extends between and to a first axial sealing ring end and a second axial sealing ring end. The first axial sealing ring end is disposed at the support ring and the outer side.

摘要： A block sealing of a rotary combustion engine having a rotating block with radially located cylinders and pistons and an outside stationary case is disclosed. Transverse and/or lateral sealings located in the stationary case fit tight to an outer surface of the block. In circular grooves, a lateral sealing of radius sealing strips with springs situated between adjacent transverse sealing strips placed in transverse grooves is located. Couplings with notches and pressure springs are located in bores of the stationary case for inserting radius sealing strips and transverse sealing strips. The radius sealing strip is provided with a cut-out for interlocking of a stop connected with the stationary case. In the side of the radius sealing strip, a longitudinal groove in which a flexible sealing element and/or transverse sealing strip is made, and at its side, it is provided with a groove in which another flexible sealing element is located.

摘要： A marine engine has a powerhead having an cylinder block, a cylinder head, and a crankcase; a supercharger providing charge air for combustion in the powerhead, wherein the supercharger discharges the charge air to an outlet duct; and a charge air cooler cooling the charge air prior to combustion in the powerhead. The charge air cooler has an upstream inlet receiving the charge air from the outlet duct and a downstream outlet discharging the charge air to the cylinder head. The downstream outlet is coupled to the cylinder head by a first one of a rigid seal device and a flexible seal device and the upstream inlet is coupled to the outlet duct by a different, second one of the rigid seal device and flexible joint device.

摘要： A seal assembly for sealing a pump shaft in a rotary piston pump configured for conveying pump-conveyed fluid comprises a sealing-fluid pump device having a pump inlet and a pump outlet. A blocking chamber is connected to the pump outlet and is disposed so as to neighbor the pump chamber of the rotary piston pump and is sealed in relation to the pump chamber by means of a first shaft seal that encloses the pump shaft. The blocking chamber by way of the pump outlet is impinged with a fluid pressure resulting from the fluid pressure differential that is generated by the sealing-fluid pump device, whereby said fluid pressure interacts with the first seal assembly to seal the pump chamber in relation to the egress of pump-conveyed fluid from the pump chamber along the pump shaft.

摘要： An insert component for a scroll compressor comprises a polymer and at least one reinforcing or lubricating particle. The insert component comprises an annular body and an axial projection. The annular body defines a first centrally-disposed opening having has a central axis extending therethrough. The annular body has a first side comprising a first contact surface configured to engage a partition plate and a second side a second contact surface configured to engage a floating seal assembly. The first contact surface defines a slope between first and second radial locations. The axial projection extends from the annular body and can be received in a second centrally-disposed opening of the partition plate. The insert component can fluidly seal both a first interface between the first contact surface and the partition plate and a second interface between the second contact surface and a floating seal assembly during operation of the scroll compressor.

摘要： An object of the present invention is to achieve favorable sealability by a simple and low-cost structure using an O-ring. A sealing structure according to the present invention is provided with: a first sealing surface formed in an annular shape on a first container structural member configuring a housing (container); a second sealing surface overlaid on the first sealing surface, formed in annular shape on a second container structural member configuring the housing; a plurality of concentric O-ring grooves formed on at least one of the first sealing surface and second sealing surface; and a plurality of O-rings fitted into the plurality of O-ring grooves. The filling ratio of the O-ring in the O-ring groove positioned on an outer side of the housing is larger than the filling ratio of the O-ring in the O-ring groove positioned on an inner side of the housing.

摘要： A tangential force internal combustion engine invention utilizes the four cycle internal combustion engine process. Working gas chambers are formed via a torroid in the housing and two adjacent piston assemblies. Pistons, ring seals, and inner seal plate elements seal this chamber. The four gas cycles are spaced over the 360 degree torroid chamber with gas ports appropriately placed. One power vane (PV) and one reaction vane (RV) connect to a central shaft with pistons attached to each vane end. The PV produces driving torque on a central shaft through an Overrunning Clutch System (OCS). At specific angles and for controlled durations the PV and VN are slowed, stopped, held to the housing, and then accelerated and coupled to the shaft. Vane movement is controlled by gears, cam ramps, and pin mechanisms operating via three independent but time-coordinated systems. The power vane has no controlled acceleration; combustion pressure serves to immediately couple this vane to the shaft via the OCS. This immediateness and direct-coupling are thought to provide efficiency.

摘要： A rotary engine including a housing and housing head enclosing a combustion chamber, a piston including an output shaft and a piston disk within the housing and rotatable on a piston rotation axis, a quadrant within the housing and around the piston and rotatable on a quadrant rotation axis, wherein the quadrant rotation axis is acutely angled to the piston rotation axis, and a post surrounding a segment of the piston disk. The post pivots relative to the piston about a post-piston rotation axis that is normal to the face of the piston disk. The post pivots relative to the quadrant about a post-quadrant pivot axis that is perpendicular to the quadrant rotation axis. The post rotates about the quadrant rotation axis relative to the housing. Combusting fuel injected into the combustion chamber expands and pushes on the piston disk to rotate the output shaft about the piston rotation axis.
