Abstract
Abstract A fluid operated pressure oscillation generator of the type which comprises a housing (10) forming an outlet passage (16) and an inlet compartment (20) surrounding the outlet passage An annular seat (11) is formed by the housing between the outlel passage and the inlet compartment, and a cover (13) detachably mounted to the housing, engages a diaphragm (12) at the periphery thereof to bias the diaphragm against the seat. An outlet (25; 30, 30a) for fluid opens into the outlet passage and faces away from the diaphragm, and means (24; 27) are provided for supplying fluid from the outside of the housing to said outlet.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
131 words
A fluid operated pressure oscillation generator comprising a housing (10) forming an outlet passage (16) and an inlet compartment (20) surrounding the outlet passage, an annular seat (11) formed by the housing between the outlet passage and the inlet compartment, a diaphragm (12) and a cover (13) detachably mounted to the housing and engaging the diaphragm at the periphery thereof to bias the diaphragm against the seat, said diaphragm forming together with the seat a valve to control a connection for operating fluid between the inlet compartment and the outlet passage, characterized by at least one outlet (25, 30, 30a) for fluid, opening into the outlet passaged(16) and facing away from the diaphragm (12), and means (24; 27) for supplying fluid from the outside of the housing (10) to said outlet.
Claim 2
Dependent Claim
131 words
A fluid operated pressure oscillation generator comprising a housing (10) forming an outlet passage (16) and an inlet compartment (20) surrounding the outlet passage, an annular seat (11) formed by the housing between the outlet passage and the inlet compartment, a diaphragm (12) and a cover (13) detachably mounted to the housing and engaging the diaphragm at the periphery thereof to bias the diaphragm against the seat, said diaphragm forming together with the seat a valve to control a connection for operating fluid between the inlet compartment and the outlet passage, characterized by at least one outlet (25, 30, 30a) for fluid, opening into the outlet passaged(16) and facing away from the diaphragm (12), and means (24; 27) for supplying fluid from the outside of the housing (10) to said outlet.
Claim 3
Dependent Claim
63 words
A fluid operated pressure oscillation generator as claimed in claim 1, characterized in that the housing (10) forms a gaseous fluid supply compartment (22) between said inlet compartment (20) and said outlet passage (16), said outlet (25) extending between the supply compartment and the outlet passage and that said means (24) for supplying fluid to the outlet are connected to the supply compartment.
Claim 4
Dependent Claim
89 words
A fluid operated pressure oscillation generator as claimed in claim 1, characterized in that said means for supplying fluid to the outlet (30, 30a) comprise a nozzle (27) and means (26; 37, 39, 46) mounting said nozzle for axial displacement through the housing (10) with one end outside the housing, said outlet (30, 30a) being arranged in a part of the nozzle adjacent said other end of the nozzle so as to be adjustable, by displacement of the nozzle, between positions inside and outside the outlet passage (16), respectively.
Claim 5
Dependent Claim
51 words
A fluid operated pressure oscillation generator as claimed in claim 3, characterized by a guide tube (26) in the housing (10), which extends between the outside of the housing and the outlet passage (16) in the transverse direction of the outlet passage, the nozzle (27) being slidable through said guide tube.
Claim 6
Dependent Claim
145 words
A fluid operated pressure oscillation generator as claimed in claim 3, characterized by an inlet passage (39) for gaseous fluid communicating with the inlet compartment (20), a valve seat (47) formed in the inlet passage between the inlet passage and the inlet compartment, said nozzle (27) extending through the inlet passage and the inlet compartment from the outside of the housing (10) into the outlet passage (16), an inlet opening (45) formed in the nozzle, and a valve member (46) on the nozzle for cooperation with the valve seat, the nozzle being displaceable between one position in which the inlet opening communicates with the inlet passage and the communication between the inlet passage and the inlet compartment is interrupted by the valve member engaging the seat, and another position in which said communication is open and the inlet opening is withdrawn from the inlet passage.
