Abstract
A side housing for a rotary internal combustion engine, has: a side wall defining first threads, the first threads extending around a central axis; a side plate having a rotor-engaging side facing away from the side wall and a back side opposite the rotor-engaging side and facing the side wall; and a nut rotatable relative to the side plate about the central axis, the nut and the side plate axially locked to one another, the nut defining second threads extending around the central axis, the side plate secured to the side wall via a threading engagement between the first threads of the side wall and the second threads of the nut.

A side housing for a rotary internal combustion engine, comprising:
- a side wall defining first threads, the first threads extending around a central axis;
- a side plate having a rotor-engaging side facing away from the side wall and a back side opposite the rotor-engaging side and facing the side wall;
- and
- a nut rotatable relative to the side plate about the central axis, the nut and the side plate axially locked to one another, the nut defining second threads extending around the central axis, the side plate secured to the side wall via a threading engagement between the first threads of the side wall and the second threads of the nut.
A rotary internal combustion engine comprising:
- a rotor;
- an outer body circumscribing a rotor cavity, the rotor received within the rotor cavity and rotatable within the rotor cavity relative to the outer body, the outer body having a rotor housing extending around a central axis, and side housings mounted to the rotor housing, the rotor cavity extending axially between the side housings, a side housing of the side housings having:
- a side wall, first threads defined by the side wall and extending around a central axis;
- a side plate having a rotor-engaging side facing the rotor a back side opposite the rotor-engaging side and facing the side wall;
- and
- a nut axially locked to the side plate and rotatable relative to the side plate, the nut having second threads threadingly engaged with the first threads of the side wall.
