A filter has a filter housing and a receptacle chamber in the filter housing into which a filter element is insertable. The filter housing has a housing cover for opening and closing an opening of the receptacle chamber. The housing cover is situated in an area of the filter housing between the oncoming flow side and the outgoing flow side of the filter element.

Filter in a filter housing

A filter device having a filter element arranged in a filter housing that can be sealed by a housing lid with a sealing ring. The medium to be filtered is supplied to the filter element through an inlet opening in the filter housing. On the filtered side of the filter element, the filtered medium is discharged through an outlet opening in the filter housing. The housing lid is constructed in two parts and includes an inner lid and an outer lid. The inner lid can be inserted into a housing opening, with the sealing ring arranged between the inner lid and the wall of the housing opening. The outer lid covers the housing opening and is connected with the wall of the housing opening by a locking mechanism.

Filter device

A multicell cyclone with a plurality of cyclone cells and a method for the production thereof, in which the cyclone cells of the multicell cyclone are combined into groups from which deposited particles are cleaned out by vacuum suction through channel structures. This permits better control of the discharge of separated particles. Vacuum suction of the separated particles can be effected, for instance, via openings () which are jointly provided for the group () of cyclone cells. The group of cyclone cells can furthermore be produced as a module, which can, for instance, be assembled from two parts () in which like structural elements of a group of cyclones are combined into one respective part. This makes it possible to optimize the separation result with little structural complexity and at low production cost.

Multicell cyclone and method for producing it

A filter device having a filter element arranged in a filter housing with a housing port closed by a housing cover with a housing ring. A medium to be purified is supplied to the filter element through an inlet in the filter housing. On the discharge side of the filter element, purified medium is discharged through an outlet in the filter housing. A pressure relief valve is integrated into the housing cover and is subjected to the pressure on the inlet side of the filter element. The housing cover is constructed in two parts and includes an inside cover and an outside cover. The pressure relief valve is mounted in the inside cover, which closes the housing port. A discharge path for discharging medium exhausted from the filter housing through the pressure relief valve is formed between the inside cover and the outside cover.
