Abstract: The invention relates to the design of a capsule for a hermetically encapsulated small refrigerator. The damping of noise is an important requirement and to this end it is conventional that the motor-compressor unit mounted in the capsule is resiliently mounted relative thereto. The radiation of noise generated in the capsule is thwarted by arranging opposite wall sections in nonparallel relationships so that a sound wave striking a wall section is prevented from being reflected to a parallel wall section which would be conducive to amplification by continuing reflection.

Abstract: A changeover valve for a bath and shower is disclosed which has alternative flow channels formed by three disks. In a first position fluid flow is shut off. In a second position fluid flows through axially aligned ports in the three disks and in a third position fluid flows through a generally U-shaped passage formed by two of the three disks. The second position provides greater flow than the third position.

Abstract: The invention relates to a diaphragm type valve assembly for a nozzle burner of a heating oil pump. This type of equipment two or more diaphragm type regulating valves or valve sections are utilized with each such valve or valve section having an individual diaphragm therefor. The improvement herein is for a valve assembly having a plurality of diaphragm type valve sections but only a single diaphragm unit is used for all of the valve sections instead of a separate diaphragm for each valve section.

A rotary carrier is attached to the shaft adjacent one of the end walls and an oblique adjusting plate is mounted adjacent the other end wall. A piston-cylinder unit extends between the carrier and the oblique plate. A pivot axis for the oblique plate includes a bearing arrangement between the plate and the adjacent end wall. A servo unit for adjustably rotating the plate about the pivot axis is provided between the plate and the adjacent end wall.

Abstract: A bonnet is mounted on an insert support and connected to a valve body to retain a diaphragm in fluid sealing relationship between the body and insert support. The insert support is rotatable relative to the housing of a fluid actuator while being retained in a fixed axial position relative to the housing. A plunger is extended through the insert support to abut against a button that abuts against one side of the diaphragm, the opposite side of which abuts against a valve seat subassembly that is resiliently urged to a valve open condition. The housing mounts a spindle which in turn has an eccentric lobe keyed thereto for moving the plunger toward the diaphragm so that the button flexes the diaphragm to move the seat subassembly to its valve closed position. Piston operated rack mechanism controls the rotation of the lobe for moving the plunger toward the diaphragm. Spring mechanism moves the piston in one direction while fluid under pressure applied to the actuator moves the piston in the opposite direction.
