摘要： Disclosed herein is a rotary internal combustion engine comprising a unitary housing member including first annularly extending wall means including an outwardly facing surface partially defining a cooling jacket extending generally circumferentially around the first wall means, and an inwardly facing surface partially defining a rotor cavity, together with second wall means extending in outwardly spaced relation from the first wall means and including an inwardly facing surface in opposing relation to the outwardly facing surface of the first wall means to further partially define the cooling jacket, and web means extending generally transversely to and joining the first and second wall means.Also disclosed herein is a rotary internal combustion engine comprising a housing assembly including a housing member having an end wall and wall means partially defining a rotor cavity extending to the end wall and having a portion in which combustion takes place and also partially defining a cooling jacket extending adjacent to the cavity portion and to the end wall, together with a cover on the housing member end wall and including a first portion further defining the rotor cavity and a second portion further defining the cooling jacket.In addition, the cover also includes wall means spaced from said rotor cavity for partially defining a second cooling jacket extending along the cover adjacent to the cavity portion, and the housing assembly also includes a coolant inlet communicating with each of the cooling jackets, and a coolant outlet communicating with each of the cooling jackets whereby one portion of the coolant flows between the inlet and the outlet through one of the cooling jackets and another portion of the coolant flows between the inlet and the outlet through the other of the cooling jackets.In further addition, the cover also includes an endless recess extending circumferentially around the second cover portion further defining the cooling jacket, together with means extending between the housing member and the cover outside of the area bounded by the endless recess for connecting the cover to the end wall, and a sealing member located in the endless recess and in sealing engagement with the cover and with the end wall to prevent loss of coolant from the cooling jacket between the cover and the housing member.

摘要： Disclosed herein is an engine block including first wall portions defining a combustion chamber, second wall portions defining a bore including a first portion extending from the combustion chamber and a second portion enlarged with respect to the first portion, third wall portions defining a water jacket in cooling relation to the second wall portions, and an elongated duct of heat resistant material communicating through the first bore portion with the combustion chamber so as to receive exhaust gases discharged therefrom, which duct is circumferentially engaged by and supported from the second wall portion at locations spaced lengthwise of the duct and extends in the enlarged bore portion in spaced relation from the second wall portions intermediate the locations, whereby there is provided a stagnant air space between the duct and the block intermediate the locations so as to reduce heat transmission from the duct.
