摘要： A foot control mechanism for a dental apparatus has a tiltable actuation member mounted on a base part and an arrangement for holding the tiltable actuation member in a neutral position, which requires sufficient force to move the actuation member in either direction from the neutral position to a switch position. To accomplish this, the structure includes a mounting arrangement utilizing a pair of spaced-apart bearings extending parallel to each other which bearings receive projections on the other element and, preferably, a catch member is provided which provides a resistant force from movement from the neutral position.

摘要： A device for surface treatment of teeth characterized by a vortex chamber divided by a diaphragm into an upper and lower portion, a reservoir discharging through an orifice which is positioned in the first portion to be closed by the diaphragm while in a first position, a pressurized gas line discharging into the first portion and extending from the first portion to a nozzle of the device so that an abradant discharged through the orifice into the first portion is mixed with the gas for discharge from the nozzle of the hand piece. The second portion of the vortex chamber includes a spring biasing the diaphragm toward the first position and a control line which receives pressurized gas from a branching line and has a regulating valve for venting the gas pressure in the second chamber to enable the diaphragm to move to the second position to enable flow of the abradant into the first portion. The device also includes a vibrating arrangement for vibrating the reservoir and the reservoir is pressurized by a pressure compensation line extending from the discharge side of the gas line to the reservoir.
