The brewing group which is used on the Rocket Appartamento is of the type called the E61 style of brewing group. This brewing group originates from the Faema E61 brewing group, but does have quite some design changes so some components are not interchangeable.
On this brewing group the water enters on the top side of the group head. This first flows true a wire mesh filter into a small nozzle. Then it enters the first brewing chamber. In this chamber you will find a valve, with a overall length of 55mm. This valve is held in place with a compression spring.
The next section is the lever assembly. In this assembly you have a shaft, when you move the lever up you will push the valve above(55mm) open and the water will flow out of the brewing group.
When you lower, close the top valve, the lever assembly. The drain valve will be pushed open. The drain valve is made up out of 2 valve types. The top one is a drain valve with a length of 52,5mm, with at the end a square shaft. The lower valve is the drain valve, which has a length of 27mm. From this valve all the exhaust water will flow out of the brewing group.
The components which are located where you lock the portafilter in place are quite generic for E61 brewing groups. The portafilter gasket has a outer diameter of 73mm and a inner diameter of 57mm. the shower screen is just a standard 60mm wire mesh screen.
