Abstract: The invention relates to a rotary piston type machine of the type which utilizes a gerotor mechanism for the expansible chambers. In the prior art the ring member of the gerotor normally or often has seven internally extending teeth and holes are normally provided in the seven teeth to accommodate seven screw bolts used for clamping together the casing parts. In the machine hereof the gerotor ring member is clamped between two side disks which in turn are disposed in counterbores of concentric casing collar portions which collar portions are in axially spaced relation to each other when in their clamped positions. Only four screw bolts are utilized for clamping together the casing parts and these bolts are positioned radially externally of the gerotor ring member and the two side disks thereof.

Abstract: The invention relates to a gerotor type motor or pump in which the valving is between the gerotor star member and the adjacent casing wall. A separate valve member, as such, is not provided. The valving includes recesses formed in the star, each of which sequentially moves into fluid communication with inlet and outlet recesses formed in the casing wall. The star member has the usual combined rotary and orbital movements and the valve recesses are accordingly formed or shaped to accommodate this compound movement.

Abstract: The invention relates to a thermostatic valve assembly for controlling the flow of a liquid therethrough. The assembly has a secondary seal for its valve stem which is made of a material which expands when contacted by a leaking quantity of the liquid being controlled. The expansion of the seal inhibits the leakage and the movement of the valve closure member. This manifestation of malfunctioning is a signal that the primary seal has become defective.

Abstract: The invention relates to fluid pressure motors and pumps of the type having a gerotor displacement mechanism. The rotary type valving for gerotor mechanisms has first and second sets of alternately arranged ports which have sequential fluid communication with ports of stationary passage which are connected to the displacement chambers. Optimum efficiency normally requires that these ports be formed and positioned with great precision. Auxiliary passages associated with the teeth of the gerotor mechanism itself, and which connect adjacent displacement chambers, effects a precise internal distribution of fluid so that only a gross of coarse fluid distribution is required of the valve ports and the fine or delicate distribution needed for optimum efficiency is performed by the auxiliary passages.

Abstract: The invention relates to a rotary piston type machine in which an externally toothed wheel and an internally toothed ring form displacement chambers, and one of the toothed elements is connected by way of a universal joint shaft to a rotary slide which, together with a valve part connected to the other toothed element, forms a diversion valve. In such machines the connection between the one toothed element and the associated rotary slide, by way of the universal joint shaft, results in a certain amount of play. This causes leading and lagging between cooperating valve parts with the result that the machine suffers a loss in capacity because of imprecise control of the rotary slide. The lead and lag angles are even greater if the universal joint shaft is coupled to the main shaft and undergoes additional torsion with increasing input and output capacity of the machine. Means are provided to slightly rotate one of the valve elements relative to the main shaft in the reversed direction to compensate for the leading or lagging tendencies referred to.

Abstract: The invention relates to a temperature responsive switch assembly of the type having a pivotally mounted lever attached to a snap action spring with the lever being pivotally movable in response to opposing forces provided by a rated spring and a vapor containing working element. The moving contact of the switch is attached to the lever. Although the vapor pressure curve of the working element is not linear, the temperature differentials between the switch on and off temperatures are kept substantially constant for the whole range of nominal temperature settings for the system. This object is achieved by an arrangement in which the line of force of the rated spring forms an acute angle with the lever which angle is of a selected magnitude that compensates for the nonlinearity of the vapor pressure curve of the working element is provided.
