A valve seat is provided on the valve body and an outlet opening is defined downstream of the valve seat which is of sufficiently restricted dimension to permit opening of the valve at a particular injection pressure and to permit maintenance of the valve open condition by means of a pressure lower than the valve opening injection pressure.

Abstract: A thermal relay is disclosed which provides a bi-metal snap disc actuator system. The actuator system includes a central divider of material having relatively low thermal conductivity and a metallic disc cup mounted on each side of the central divider. A bi-metal snap disc is located in each disc cup and a separate heater is provided to respectively heat the discs. The discs are mounted so that they tend to move toward each other at normal environmental temperatures and a bumper is interposed between the discs to cause them to move in with snap action in the unison. The actuator operates two switches. In one embodiment, one switch is normally closed and the other switch is normally open. In another embodiment, both switches are normally open.

Abstract: A trip-free manual reset thermostat is disclosed in which a bimetal snap disc is positioned so that one edge portion engages a movable contact support arm and opens the contacts when the disc operates to its operative condition. A manual reset member is operable to apply a force to the center portion of the disc in the direction of contact opening, causing the edge of the disc to engage fixed stops and to thereafter move the disc to its reset position. The resetting force is applied in the same direction as contact opening movement so that the operation of the reset member maintains the contacts in an open condition even when the disc has been pushed through to the reset condition. The manual reset member is, therefore, incapable of causing switch closure.

Abstract: An expandable abrasive tool is provided with an axially-extending slot receiving a single abrasive element and multiple axially aligned and axially spaced apart pockets located circumferentially from the slot with each pocket fixedly receiving an individual centering element for properly positioning and supporting the abrasive element in the hole. The axially spaced apart pockets space the centering elements apart in end-to-end relation and thereby allow torsional flexing of the tool body during hole machining without damaging the brittle centering elements. In an alternative version, multiple centering elements are received in spaced apart end-to-end relation in a single axially elongated slot instead of in individual pockets.

Abstract: A temperature-sensitive element on a rotatable drum of a copying machine changes a characteristic in response to a temperature on said drum. The characteristic is employed to control a temperature signal. The temperature signal from the drum is connected to stationary portions of the copying machine through sliding contacts. A control circuit responds to the temperature signal to control the energization of a heater to maintain the temperature of the drum at a predetermined value. The temperature signal and the control circuit complement each other to avoid errors caused by changes in resistance in the sliding contacts. In one embodiment, the temperature signal is a controlled current, independent of resistance in series with it, and the control circuit measures the current.
